1.1 Pyxis Major Features
The SP-910 analyzer shown in Figure 1 is a combination of photometer and
fluorometer. It provides colorimetric measurements at 7 LED wavelengths, fluorometric
measurement of fluorescent tracer PTSA and fluorescein, and nephelometric turbidity
measurement using white LED and infrared LED as excitation sources. The SP-910 is
pre-calibrated for colorimetric measurements of analyses common in industrial water
treatment and other water testing applications in the laboratory or in the field, such as
measuring chlorine, phosphate, iron, and copper. Main features include:
The SP-910 is pre-calibrated for measuring PTSA (pyrenetetrasulfonic acid) in the
range of 0 to 300 ppb. The fluorescence PTSA measurement is automatically
compensated for sample color and turbidity interference.
The SP-910 is pre-calibrated for measuring fluorescein in the range of 0 to 600
ppb.
The SP-910 is pre-calibrated for measuring turbidity in the range of 0 to 200 NTU.
Automatically select the primary wavelength according to the method selected and
switches to the secondary wavelength to extend the primary measurement range.
Figure 1 Insert the Sample Vial
Display a concentration-time profile curve in a colorimetric measurement. The user
can terminate the timing process and take a reading if the displayed concentration
reaches a plateau before completing the predefined time period.
The user can update the calibration parameter of any pre-calibrated colorimetric
method by testing a standard solution first and then following a setup procedure to
update the calibration parameters.
1.2 Unpackaging the Instrument
Remove the instrument and accessories from the shipping container and inspect each
item for any damage that may have occurred during shipping. Verify that all items

listed on the packing slip are included. If any items are missing or damaged, please
contact Pyxis Customer Service at [e-mail].
1.3 Standard Accessories
•Sample Vials - two 10 ml, round, 0.78 inch (20 mm) pathlength, glass vials,
which can be used for all measurements including turbidity and fluorescence
measurements
•4 AA alkaline batteries
•Instrument Manual, also available from www.pyxis-lab.com
1.4 Optional Accessories
•25 ml sample vial
•100 ppb PTSA standard in a 500 ml brown plastic bottle
•50, 250,and 500 ppb fluorescein standards in a 500 ml brown plastic bottle
1.5 Sample Vial Compartment
The sample vial compartment is shown in Figure 1, along with a 10-ml sample vial.
When the sample vial is inserted into the sample vial compartment, the triangular mark
on the sample vial should be aligned approximately with the 6 o’clock position of the
sample vial compartment or any position consistently.
The sample vial compartment should be kept clean. A small amount foreign material
could significantly affect turbidity and fluorescence measurement results. Use a soft
cloth or lint free paper tissue to clean sample vial compartment periodically. Remove
debris, scale, and deposit promptly.
1.6 Light Shield Cover
The light shield cover is shown in Figure 2. The light shield cover can be conveniently
slid between the open and closed positions. The light shield cover is held firmly at the
rest positions by permanent magnets.
The light shield cover should be in the closed position during storage, transportation,
and measurements, especially during the turbidity and fluorescence measurements.
When turned on, The SP-910 carries out self-diagnosis including checking the
performance of a variety of optical devices. The light shield door shall be at the closed
position to shield interference from ambient light during self-diagnosis.
Care should be taken to avoid water or debris being trapped in the track of the light
shield door.
