Introduction
Ŷ Operating Principle
The analyzer is equipped with two optical detection modules. One is a photometer and
the other is a uorometer. The photometer can measure absorbance at 10 dierent
wavelengths (340, 405, 450, 500, 550, 570, 600, 630, 660, and 700 nm) to accommodate
various chemical and immunological reaction protocols. The measured absorbance is
converted into the concentration of the analytes.
For endpoint reactions, the nal absorbance is used for the calculation of the concentration
of the analyte.For kinetic reactions, the absorbance change during a predetermined time is
utilized for the calculation of the concentration instead of the nal absorbance.
The uorometer utilizes a time-resolved uorescence method to support high-sensitivity
immunoassay based on europium nanoparticle lables. A 365 nm LED is used as an
excitation light source and a red-sensitive photomultiplier tube is used as a photodetector.
The measured uorescence intensity is converted into the concentration of the anlayte.
