System Description
1.1 Overview
The
BS-120/BS-130/BS-180/BS-190
is
a
fully-automated
and
computer-controlled chemistry analyzer designed for in vitro quantitative
determination of clinical chemistries in serum, plasma, urine and CSF
(Cerebrospinal fluid) samples. BS-120/BS-130/BS-180/BS-190 Chemistry
Analyzer consists of the analyzing unit (analyzer), operation unit (personal
computer), output unit (printer) and consumables.
1.2 System Components
BS-120/BS-130/BS-180/BS-190 Chemistry Analyzer realizes the ”two-disk +
one-probe + one-mixing bar” scheme, which means one reaction disk, one
sample/reagent disk, one sample probe and one mixing bar. Reaction disk is
where cuvettes are placed; sample/reagent disk is where sample and reagent
containers are placed; sample probe is used for dispensing R1/R2/S; mixing
bar is used for mixing after S or R2 has been added. The photometric system
adopts filter wheel photometer. The cuvettes are replaced manually after the
tests are finished.

1.3 Functions
The general working procedure of the BS-120/BS-130/BS-180/BS-190 is as
follows:
1. All mechanical units are initialized.
2. The sample/reagent disk rotates to R1 aspirating position, and the probe
aspirates reagent from a bottle on the sample/reagent disk.
3. The reaction disk carries the cuvettes to the sample/reagent dispensing
position, and the probe dispenses reagent to a cuvette.
4. R1 is incubated in reaction cuvette for several periods.
5. The sample/reagent disk rotates to sample aspirating position, and the
reaction disk carries the cuvettes to the sample/reagent dispensing
position, then the probe dispenses the sample in the reaction cuvette.
6. With sample dispensed, the reaction cuvette rotates to mixing position for
stirring.
7. In case of single-reagent tests, the reaction begins. When defined time is
over, the reaction ends.
8. In case of double-reagent tests, when sample is dispensed and sirred, the
sample/reagent disk rotates to the R2 aspirating position, and the probe
aspirates reagent from the specified bottle on the reagent disk.
9. The reaction disk carries the cuvettes to the sample/reagent dispensing
position, and the probe dispenses reagent to a cuvette.
10. With R2 dispensed, the reaction cuvette is carried to the mixing position
for stirring.
11. During the first and second rotation of each period, the reaction cuvette
receives photometric measurement.

2.2.2.1 Timing for Main Components
The working period of BS-120/BS-130 is 36 seconds, so its throughput is 100
tests/hour (3600/36). During each working period, the reaction disk rotates three
times and stops three times. During each stop, the sample probe can dispense
sample, first reagent and second reagent respectively. Therefore, the throughput
is not affected no matter it is single-reagent test or double-reagent test because
both of them have the same test efficiency. The practical throughput is affected
by reaction time and cuvettes replacement.
The system collects photometric data two times during each period. Therefore,
the interval between two absorbance readings is 18 seconds for each test.
The movements of major moving parts are shown in the following table.

The working period of BS-180/BS-190 is 16 seconds, so its throughput is 225
tests/hour (3600/16). During each working period, the reaction disk rotates two
times and stops two times. During each stop, the sample probe dispenses R1
and sample and stirs the sample, and dispensing R2 is done in a single period.
Therefore, the throughput is affected by single or double reagent tests. The
practical throughput is affected by reaction time and cuvettes replacement.
The system collects photometric data two times during each period. Therefore,
the interval between two absorbance readings is 16 seconds for each test.

4.6 Photometric Unit
4.6.1 Introduction
Chemistry analyzer is a typical instrument which features in optics，mechanics, electronics
and arithmetic. The photometer is one of the key components of the instrument and
determines directly the precision and accuracy of measurement of the system.
The light source irradiates directly the cuvette in the photometer. A combined light passes
through an optical interference filter and turns to a monochromatic light. The
monochromatic light passes through the cuvette and is received by the photoelectric
detector and then is converted into an electrical signal by the photoelectric detector. The
microprocessor calculates the concertration of the solution in the cuvette by contrasting
the optical intension of the light before and after passing through the solution. The multiple
monochromatic wavelengths in the pototometer system are obtained by utilizing the filter
wheel. Rotate the filter of a specific wavelength to the light path while performing the
colormetric measurement.
4.6.2 Components of Photometric Unit
The lens 1 converges the light beam emitted from the light source to the filter. The lens 2
collimates the monochromatic light beam aimming to the reaction cuvette. The light is
absorbed when passing through the solluton and then is converged at the photodiode via
the lens 3. Finally the photodiode converts the light signals into electric signals and then
outputs them. From the outside to the inside of the reaction disk, the whole configuration
of the light path is shown in Figure 4-29.

Adjustment of Photometer
4.6.4.1 Adjusting Photometric Position of Reaction Disk
The photoelectric collecting position in the reaction disk depends on the installing
position of the coder sensor of the reaction disk. Any slight movement of the sensor will
change the photoelectric collecting position and then affect the performance of
photoelectric collection. Therefore, don’t remove the coder sensor unless it is
necessary.
CAUTION
Don’t remove the coder sensor of the reaction disk unless it is
necessary.
It is necessary to check the photoelectric collecting position after replacing the the
coder sensor or tightening the screw of the sensor bracket,
The adjustment of photometric position is carried out by using an oscillograph to
measure the photoelectric analog signal and the AD collection start signal. The probe
of the oscillograph should be connected to the specified signal test point.
The adjusting steps are described as follows.
1． Make sure to turn off the power switch of the analyzing unit.
2． Open three table panels to expose the AD housing assembly. (See Figure 4-37)
4-32

CAUTION
Before opening the table panels, pull up the sample probe and the
mixing bar so as to operate conveniently.
WARNING
Be careful not to be injured by the sample probe.
BIOHAZARD
Don’t touch the the sample probe with naked hand.
3． Open the shielding box of the AD housing assembly(See Chapter 4.6.3.3 ), and
connect two probes of the oscillograph to the AD start signal(RC and GND) and the
analog signal (V3), then connect the earth terminal to the ground.

Figure 4-39 Photometric Instruction
6． When the oscillograph displays the complete waves circularly shown in Figure
4-40, press STOP on the oscillograph. The waves are frozen.
Figure 4-40 Photometric Wave
7． Magnify the waves shown above and check whether the AD start signal is in the
middle of the photometric analog signal (See Figure 4-41). If yes, the photometric
position is correct.
4-34
4 Units Description
Figure 4-41 Photometric Wave Feature
8． If the AD start signal is in the decreasing part of the photomectric analog signal
instead of the middle part, the photomectric position is not proper and must be
adjusted by moving the coder sensor of the reaction disk. If the AD start signal is
on the left, then move the sensor along clockwise. If it is on the right, move the
sensor along counter-clockwise. The left panels, right panels and front panels
should be removed for adjusting the sensor.
10. Adjust the coder sensor of the reaction disk: the sensor is fixed on the sensor
bracket and only the sensor bracket should be adjusted.See Figure 4-42, loosen
the three screws and adjust the sensor bracket position according to the
photoelectric wave. After completing the photomectric position adjustment, tighten
the three screws.
11. After finishing the above operation, send Ordinary Rotate&Measure Instruction
and check the photometric waves again.

4.6.4.2 Adjusting Offset of Filter Wheel
After moving the sensor of the filter wheel or removing the filter wheel, you should
adjust the offset of the filter wheel and set parameters.
Refer to Chapter 8.5.1 for details about adjusting the filter wheel offset.
4.6.4.3 Adjusting Signal Gain of Photometric Unit
The purpose of adjusting signal gain is to ensure that the air blank AD value is within
48000 -60000 after replacing new lamp.
CAUTION
If air blank AD value is lower than usual after replacing new lamp,
check whether the surface of the lamp or the filter is dirty.
Refer to Chapter 8.5.2 for details about adjusting signal gain of the photoelectric unit.
Precaution for signal gain adjustment：
：
1． It is not recommended to extend the service life of the lamp by adjusting the signal
gain.
4-36
4 Units Description
2． The signal gain of the photoelectric unit has been configured properly before the
analyzer is sold to the custumer. When an alarm occurs indicating weak light,
replace the lamp directly instead of adjusting the signal gain. Usually it is
unnecessary to adjust signal gain after replacing the lamp. However, after doing
that, you should check whether the air blank AD exceeds the range on the
Maintenance-Daily Maint. page of the operating software. If not, click new lamp to
complete replacing new lamp. If yes, you need to adjust the signal gain.
3． Adjust the signal gain: It is recommended to use both automatic adjustment and
manual adjustment. Adjust signal gain automatically, and then adjust manually.
4.6.4.4 Checking Performance of Photometer
It is recommended to check the performance of photometer under the following
conditions:
1． The analyzer installation is completed.
2． The lamp is replaced or re-installed.
3． The filters are replaced or re-installed.
4． The measurement data is abnormal.
The checking method is as follows.
Request the tests that use water as sample and reagent in operating software.
For replacing or re-installing the lamp, request 20 times replicated tests in which the test
wavelength parameter is set as 340 and 405nm.
For other cases, it is necessary to check performance of each walvlength. So request 5
times replicated tests under each diffirent wavelength respectively (40 tests total).
The test time is set as 0~35 and other parameters are not limited.
Check reaction curve and data of each test after completing all the tests. The difference
between the minimum absorbance value and the maximum value for each detecting
point should be less than 30.
If the results can’t be compliant with the requirement, please check the following details.
If the test data from all wavelengths are abnormal, make sure that the installaion of
lamp is ok, including whether the pottery socket is stable and whether the lamp is
installed in the proper position.
If the test data from a part of wavelengths are abnormal, check whether the filter is
installed in the right way or whether the filter surface is dirty or has nicks
Check whether the lamp intensity is stable.
If the test data from a few cuvettes can’t be compliant with the requirement, it can
be concluded that there is no problem with the photometer and then check whether
there are air bubbles in the cuvette or whether the surface of the cuvette is dirty. If
yes, the photomethic performance is ok and the abnormal data can be ignored.
Check the performance again after resolving all of the above problems. If there are still
abnormal data, please contact the development engineer.

10.1 Reaction Type
The system provides three reaction types for measurement: Endpoint, Fixed-time and
Kinetic.
10.1.1 Endpoint
The endpoint or, more correctly, equilibrium method, is most ideal. The reaction reaches
equilibrium after a period of time. Since the equilibrium constant is very large, it can be
considered that all substrates (analytes) have changed into products, and absorbance of
the reaction liquid does not change any more. The absorbance change is directly
proportional to the analytes concentration.

t2
t3
t
As shown in Figure 10-1, t1 is the time when the reagent is added, and t 2 is the time
when the sample is added. The reaction starts when they are mixed. At t 3 the reaction
reaches equilibrium and the absorbance reading is taken. The reaction period is t 2 to
t3 .

t
As shown in Figure 10-2 , t1 is the time when the first reagent is added, and t 2 is the
time when the sample is added, incubation starts when they are mixed. t 3 is the time
when the second reagent is added, then the reaction starts when they are mixed. At t4 the
reaction reaches equilibrium and the absorbance reading is taken. t 2 to t 3 is the
incubation period and t 3 to t 4 is the reaction period.
The endpoint reaction is largely insensitive to minor changes in such condition changes as
amount of enzyme, pH and temperature, provided the changes are not significant enough
to affect the reaction time.
10.1.2 Fixed-Time
For the fixed-time reaction method (namely, first-order kinetic method or initial rate
method), the reaction velocity (v), within a specific period, is directly proportional to the
substrate concentration [S], namely, v=k[S]. As the substrate is consumed continuously,
the reaction velocity becomes smaller and smaller, and so does the change rate of the
absorbance. It takes much time for such a reaction to reach equilibrium. Theoretically, the
absorbance reading can be taken at any time. The reaction can, however, become steady
only after a delay because it is complicated at the beginning and there are miscellaneous
reactions due to the complex serum compositions. For any first order reaction, the
substrate concentration [S] at a given time after the start of the reaction is given by the
following:
[S ] = [S 0 ]× e − kt
Where,
[S0] - initial substrate concentration,
e
- base of the natural log,
k
- rate constant.
The change in substrate concentration ∆[S] over a fixed-time interval, t1 to t 2 , is related
to [S0] by the following equation:
[ S 0] =
− ∆[ S ]
e
− kt1
−e
− kt 2
That is, within a fixed time interval, the change in substrate concentration is directly
proportional to its initial concentration. This is the general property of first order reactions.
Within this interval, absorbance change is directly proportional to the analytes
concentration.

As shown in Figure 10-3, t1 is the time when the reagent is added and t 2 is the time
when the sample is added. The reaction starts when they are mixed. From t 3 the
reaction becomes steady and t 4 is the time to stop monitoring the reaction. t 2 to t 3 is
the lag period, and the absorbance readings are respectively taken at t 3 and t 4 .

t
As shown inFigure 10-4 t1 is the time when the first reagent is added, and t 2 is the time
when the sample is added, and then the mixture absorbance reading is taken after they
are mixed. t 3 is the time when the second reagent is added, then the reaction starts
when they are mixed. At t4 the reaction reaches equilibrium, and t 5 is the time to stop
monitoring the reaction. t 2 to t 3 is the incubation period, and t 3 to t 4 is the delay
period. The absorbance readings are respectively taken at t 4 and t 5 .
The fixed-time reaction is demanding more technically than the equilibrium method.
Because reaction rate is measured at two different points, all the factors that affect
reaction rate, such pH, temperature, and amount of enzyme, must be kept constant from
one assay to the next, as must the timing of the two measurements. A reference solution
of the substrate must be used for calibration.
10.1.3 Kinetic
For the kinetic method (namely, zero-order kinetic or continuous-monitoring method), the
reaction velocity is not related to the substrate concentration and remains constant in the
reaction process. As a result, for a given wavelength, the absorbance of the analytes
changes evenly, and the change rate (∆A/min) is directly proportional to the activity or
concentration of the substrate. The kinetic method is usually used to measure enzyme
activity.
In fact, it is impossible for the substrate concentration to be high enough, and the reaction
will be no longer a zero-order reaction when the substrate is consumed to a certain
degree. Therefore, the theory only stands within certain period. In addition, the reaction
can become steady only after a certain period of time, because the reaction is

complicated at the beginning and there are miscellaneous reactions due to the complex
serum compositions.

10.2.1 Calculating Absorbance
The system measures the light intensity through photoelectric conversion, linear
amplification and AD conversion. For the light intensity signal I i of Channel i, the AD
output Di is:
Di = K pe ⋅ K a ⋅ K ad ⋅ I i
Where,
K pe - photoelectric conversion factor
K a - linear amplification factor
K ad - AD conversion factor
Di - test data of Channel i
I i - light intensity of Channel i
So,

Where,
Ai
- absorbance of Channel I,
Di 0 - background AD output,
Di
- AD output after the substrate is added.
In theory, when the lights are off, the AD output of each channel will be zero. In practice,
because of the existence of dark current, there is still a background output Dibackground ,
which should be deducted. Then, the complete absorbance formula should be:

10.2.2 Calculating Response
For the system, the response (R) is defined as the absorbance change before and after
the reaction, or the absorbance change rate during the reaction process.
The formula for calculating the response (R) is closely related to the analytical method
(kinetic, fixed-time and endpoint), the number of reagents (single or double), and the
number of wavelengths (single or double). They are respectively detailed in the following
sections.

Double-wavelength (for both single-reagent and double-reagent)
The calculation method is similar to that for single-wavelength reaction, except that in

10.2.3 Calculating Calibration Parameters
The system provides two calibration methods: linear calibration and nonlinear calibration.
Linear calibration includes one-point linear calibration, two-point linear calibration and
multi-point linear calibration. They are mainly used for tests determined by colorimetry.
Nonlinear calibration includes Logit-Log 4P, Logit-Log 5P, Exponential 5P, Polynomial 5P,
Parabola and Spline. They are mainly used for tests determined by turbidity.
