1.1 Pyxis Major Features
The Pyxis SP-900 analyzer shown in Figure 1 is a combination of photometer and
fluorometer. It provides colorimetric measurements at 6 LED wavelengths, fluorometric
measurement with 365 nm excitation and 410 nm emission, and turbidimetric
measurement using a white LED as the excitation source. Pyxis SP-900 is pre-
calibrated for colorimetric measurements of analytes common in industrial water
treatment and other water testing in the laboratory or in the field, such as chlorine,
phosphate, iron, and copper. Main features include:
