Test Procedures:

1 Power on the analyzer, then start up and initialize it. The initialization includes resetting mechanical assemblies, switching on the lamp and incubating by the temperature unit. You can’t start testing unless the lamp becomes steady and temperature of the reaction disk reaches 37˚C constantly. This process may take about 15-20 minutes.

2 At the beginning of test, the probe and the mixing bar are washed.

3 The probe dispenses R1 to the cuvettes. It may skip to the next one when encountering a dirty cuvette.

4 The probe dispenses samples to the cuvettes. When the incubation time set for double-reagent tests is up, R2 is dispensed.

5 After reagents and samples are dispensed for a batch of tests, the probe and the mixing bar will be washed.

6 When the test is finished, a prompt will appear to inform you to replace the cuvettes manually.

7 When finishing all the tests, exit the system software and the analyzer will perform the shutdown procedure: washing the probe and bar with detergents, resetting the mechanical assemblies.

The analyzing unit of the BS-200 consists of the dispensing system, temperature control system, photometric system, fluid system and etc.

3.2.1 Dispensing System

The dispensing system consists of the probe module, mixing bar module, sample/reagent disk assembly and reaction disk assembly.

3.2.1.1 Probe Module and Bar Module

The mixing bar module is the same as the probe module, except that the knurled axis is 3cm shorter.

The drive assemblies of the probe module and the bar module have a horizontal and vertical photoelectric switch, which are used for defining horizontal and vertical initial positions of the probe and bar. The horizontal and vertical step motors precisely control the horizontal and vertical movements of the probe and bar. The synchronous belts serve as the gearing.

The shaft and the spline pair must corporate with each other precisely, so they should not be replaced separately.

3.2.1.2 Sample/reagent disk, reaction disk assemblies

The sample/reagent disk assembly consists of the sample/reagent disk and bearing support. The reaction disk assembly consists of the reaction disk and bearing support.

The two bearing support are different in their upper connection block and their coders.

The gaps of the coder define the positions where the disk should stop at. Each coder has two transducers for inducing the rotation and initial position of the disk.

6-Cover 7-Temperature-controlled chamber 8-Bottom heater

Temperature-controlled chamber

The temperature-controlled pot, heat-insulator, photoelectric seat and the cover constitute an enclosed cavity, in which the reaction disk rotates. The heat-insulator, with good heat insulation, protects the temperature-controlled chamber from being interfered by external environment. There is a gap on the cover, which is used for loading/unloading reaction cuvettes manually.

Heater

Top heater: square in shape, 110/220VAC, 125W

Bottom heater: ring in shape, 110/220VAC, 350W

Total power: 475W.

The heaters compensate the heat for incubating the reagents and maintaining the temperature of the temperature-controlled chamber.

Fans

Fans are used in series in the temperature-controlled chamber, so as to circulate the air in the chamber and enhance the convective heat exchange. There are four fans in the chamber. All of them have alarm function.

Temperature transducer

It feeds back the air temperature at the position near the reaction cuvette. With an overheat protection switch, the temperature transducer can disconnect the pot from the power supply to avoid overheat and fire when the temperature inside the pot is up to about 55°C. The switch can also be reset automatically when the temperature inside the pot decreases to about 35°C.

Control

PID control. PID parameters can be self-adjusted at any time.

Safety precaution

The power of the two heaters is 110/220V, and the total power is nearly 0.5kW, so the following precautions are considered: grounding protection of the

3.2.2.2 Reagent Preheating

The preheating assembly consists of two aluminum plates, a Teflon tube, heating components, transducer, temperature switch, thermal conductive colloid, a section of tubing and the probe. The transducer detects the temperature, and then transmits it to the temperature controller. Thus the heating assembly is controlled, and the temperature is controlled.

The temperature of the thermal source of the preheater is 45°C. The initial temperature of the reagent is 2-8°C when it is taken out of the refrigerator. When the reagent passes the heater, its temperature increases quickly. Then the reagent is added into the reaction cuvette and the preheating process is finished.

3.2.3 Photometric System

The photometric system consists of measurement photometric systems and a reference photometric system. The former provides 8 monochromatic lights to measure the absorbance of the reaction liquid in the rotating reaction cuvettes, while the latter compensates the former to make the measurement more accurate.

In the BS-200, the 700nm is optional. You can see the fiber of 700nm in the analyzing unit but the fiber does not work because there is no photoelectric conversion board for the wavelength.

The lamp gives out the lights, which are divided with optical fibers. One becomes the reference light, monitoring the working status of the lamp. Other 8 monochromatic lights go into the cuvettes of the reaction disk, transmit through the cuvettes and optical filters of specific wavelengths, and then go to the photoelectric conversion board. The electric signal, converted from the optical signal, is amplified and converted on the A/D conversion board, and then sent to the main control board, which will submit the absorbance to the PC for calculation.

The absorbance is taken when the reaction cuvette rotates to the corresponding optical path. Absorbance of 8 cuvettes can be taken simultaneously.

This procedure is applicable to all four-pin optical couplers used on the analyzer.

1 There are two labels E and S on the optical coupler. E stands for emitter and S stands for sensor.

2 A constant DC 5V or above is needed.

3 Usually the two pins on the E terminal are red and black or red and blue. The red end is for high level.

The E terminal that is powered by 5V is in serial connection with a 220Ω resistor.

4 Usually the two pins on the S terminal are white and green. The white end is for high level.

The S terminal that is powered by 5V is in serial connection with a 5.1KΩ resistor.

5 Voltage of the white end can be measured with a multimeter.

When the optical coupler is not shielded, the white end has a low level which does not exceed 0.6V; otherwise it has a high level which exceeds 4.4V.

If the measured voltage is within the above thresholds, the optical coupler runs normally.
