Figure 5. PTSA Measurement
Deionized water (DI) as the blank calibration solution and the 100 ppb PTSA calibration s
During the fluorescence measurement to determine the PTSA concentration, the SP-910 checks the
sample turbidity. If the sample turbidity value detected is greater than 40 NTU, The SP -910 will display a
warning. For best results, the sample should be filtered if turbidity exceeds 40 NTU.
Sample color causes a lower PTSA concentration to be measured. The SP-910 automatically
compensates for sample color. If the sample color is too intense, The SP-910 will display a warning.
For best results, ensure that the sample vial is clean. Wipe off water on the outside wall of the sample vial
using a lint-free tissue paper. Fill the sample vial to the 10 ml mark. If the sample contains air bubbles, tap

14
and their corresponding Hach® program number. Hach® reagents for 10 ml sample can be used for the
test.
5.3
Single Timing Step Method
Most of colorimetric methods have only one timing step. As an example, in the DPD free chlorine method,
it takes one minute for the DPD powder reagent to completely react with chlorine in the water sample.
The DPD free chlorine method has a single one-minute timing step. Figure 13 shows the main page of a
method with a single timing step.
Figure 13. Single Timer Method
5.4
Single-Vial Procedure
1. Place the sample vial filled with the water sample in the SP-910 sample vial compartment and
press the ZERO button. The SP-910will display the page shown in Figure 13.
2. Take the sample vial out and add the reagent to the sample vial.
3. Place sample vial back into the sample vial compartment and press the timer button TMR1. The
SP-910 will start to monitor the reaction between the reagent and the species you want t o
measure in the water sample. The concentration is shown in the chart as a function of time
(Figure 14).
4. When the timer reaches the preset time and the reaction is complete, the value of concentration
will be shown on the top right corner of the page.
5. The rate of the reaction is often faster than the standard pre-set time, which will become apparent
from the concentration-time plot. You can press the STOP button to stop the timer and terminate
the timing step. The last read concentration value will be displayed on the top right corner of the
page after you terminate the timing step.
Figure 14. Concentration as a Function of Time
5.5
Two-Vial Methods
15
Some colorimetric methods require using two vials. The water sample is added to two identical vials. One
vial is being used to zero the colorimeter, referred as to the prepared blank. A reagent is added to the
other vial, referred as to the prepared sample. The absorbance value is determined from the prepared
sample.
If the method requires two or more reagents, the prepared blank could be the resulting solution after one
or more reagents have been added to the sample.
The following procedure is typical for two-vial methods:
1. Place the prepared blank into the SP-910 sample vial compartment and press the ZERO button
to zero the instrument.
2. Place the prepared sample into the SP-910 sample vial compartment and press the TMR1 button
to start the method timer.
3. When the timing step is completed, the measured concentration will be displayed on the top of
the page. The timing step could be terminated earlier by pressing STOP button.
4. Optionally, the SP-910 can be re-zeroed using the prepared blank after the timing step is
completed or terminated. The blank reading will be subtracted from the measured concentration
value, and the displayed concentration value on the top-right corner will be updated. This step is
optional. It is only necessary if the prepared blank changes its color during the timing period.
5. Optionally, the prepared sample vial can be put back and read again by pressing the READ
button if the blank is re-zeroed after the timing step is completed or terminated. A new
concentration value based on the last absorbance value measured will be calculated and
displayed.
5.6
Multiple Timing Steps Method
Some colorimetric methods have two or three timing steps. The SP-910 shows a count-down timer for the
timing steps before the last timing step ( Figure 15). During these timing steps, one or more reagents are
added to the sample, or operations such as swirling the vial to mix the reagent and the sample are being
performed. These methods usually use one vial for the prepared blank and the other for the prepared
sample.
Figure 15. Multiple Timer Method
In order to show the concentration-time curve as shown in Figure 14 during the last timing step, The SP910 must be zeroed using the prepared blank before the last timing step. Thus, the last timer button will
not be selectable until the SP-910 has been zeroed using the prepared blank. Multi-timing step Hach®
methods require zeroing the colorimeter using the prepared blank after the last timing step is completed.
The SP-910 can optionally be re-zeroed using the prepared blank after the last timing step. The blank
16
value measured will be subtracted from the concentration value measured at the end of the last timin g
step. Optionally, the READ button could be pressed to read the prepare sample again.
The following procedure is typical for methods having two-timing steps:
1. Press the TMR1 button to start the first timer. Complete the necessary operations to
prepare the blank and the sample.
2. Place the prepared blank into the SP-910 sample vial compartment and press the ZERO
button.
3. Place the prepared sample into the SP-910 sample vial compartment and press the TMR2
button to start the second timer. The SP-910 will display the measured concentration as a
function of time as shown in Figure 14.
4. When the timing step is completed, the measured concentration will be displayed on the
top right of the screen. The timing step could be terminated earlier by pressing STOP
button.
5. Optionally, The SP-910can be re-zeroed using the prepared blank after the timing step is
completed or terminated. The blank reading will be subtracted from t he measured
concentration value, and the displayed concentration value on the top -right corner will be
updated. This step is optional. It is only necessary if the prepared blank changes its color
during the timing period.
5.7
Advanced Methods
The SP-910 provides 7 LED wavelengths and can measure absorbance values at multiple LED
wavelengths. Consequently, the SP-910 can provide many predefined advanced methods that
traditionally require complex and often expensive lab testing procedures.
5.7.1
Low range, direct reading chlorine dioxide, 0 to 35.0 ppm
The maximum absorption bank of aqueous chlorine dioxide is around 360nm. The SP-910 has a 365nm
UV LED and can be used to directly measure chlorine dioxide. It offers a much lower detection limit (0.2
ppm) than direct methods available from other portable colorimeters having only light sources in the
visible range.
Select ClO2D in the method selection page and carry out the following steps to measure chlorine dioxide:
1. Place a vial filled with deionized water into the vial compartment and press the ZERO button
to zero the SP-910.
2. Discard the deionized water and fill the same vial with the sample. Place the vial into the vial
compartment and press READ button to read. The measured chlorine dioxide concentration
will be displayed in the top of the method page.
5.7.2
Turbidimetric Anionic Polymer Method
1. Add polymer reagent 1 to 10 ml sample and inverse the sample vial 5 times to mix the
reagent with the sample. Place the sample via to the sample vial compartment.
2. Press on ZERO.
3. Add polymer reagent 2 and press on TMR1 to start the five minutes timer.
17
4. Gently inverse the sample via for 10 times and place the sample vial to the sample vial
compartment.
5. Polymer concentration will be measured and displayed when the five-minute timer is reached.
The polymer concentration is shown as ppm PAA (polyacrylic acid) equivalent.
5.7.3
Direct Reading Bleach Percent Method, 0 to 15%
The SP-910 has a 365nm UV LED and other deep blue LEDs that can be used to directly measure
bleach concentration in the range of 0 to 15%. No reagent is required for the method and the displayed
result is the sodium hypochlorite concentration in percentage.
Select BLCH in the method selection page and carry out the following steps:
1. Press the OK key to enter the temperature input interface. Enter the temperature of the
sample.
2. Place a vial filled with deionized water into the vial compartment and press the ZERO button
to zero the SP-910.

Note that the absorbance values measured with the SP-910 is generally smaller than those measured
with a spectrophotometer equipped with a monochromatic light source or detector. The SP -910
absorbance values should, however, linearly correlate with the absorbance values measured with the
spectrophotometer. Thus, for any colorimetric system, The SP-910 absorbance follows Lambert-Beer law.

10 Maintenance
Use a soft cloth or lint free paper tissue to clean the sample vial compartment periodically. Remove
debris, scale, and deposit promptly.
Although The SP-910 is protected from water damage, it is a good practice to avoid water entering
the sample vial compartment and becoming trapping underneath the navigational control pad.
Deposits left behind when the water is evaporated could affect Pyxis performance.
The SP-910 should be stored in the temperature range of 0 to 140°F (-18 to 60°C) and relative
humidity less than 85% at 106 °F (41 °C). Do not leave the SP-910 in a parked vehicle. The
temperature inside a parked vehicle can reach above 150 °F in summer and -20 °F in winter.
Exposing the SP-910 to extreme temperature or humidity will cause a gradual decay in performance
of fluorescence measurements and require more frequent calibrations.
During storage and transportation, do not leave a sample vial in the sample vial compartment. Close
the lid of the sample vial compartment during storage and transportation.
Replace batteries when the SP-910 displays a warning message indicating LOW BATTERY voltage.
Remove batteries from the SP-910 battery compartment if the SP-910 is going to be placed in
storage for a long period time.
30
When the SP-910 is shipped, a desiccant pack is included in the desiccant compartment underneath
the cover of the battery compartment. It is recommended that a new desiccant pack is replaced each
time the batteries are replaced.
11 Troubleshooting
The SP-910 will prompt a warning message if it detects an abnormal condition or operation. On
screen prompts direct the user to take appropriate corrective actions in most cases.
If an unspecific error occurs or the SP-910 cannot be turned on, reboot the instrument by taking a
battery out of the battery holder and re-install the battery.
If the SP-910 has been idle for more than two months and cannot be turned on, replace all four
batteries with four new AA alkaline batteries.
