Measurement Method
It is based on fluorescent optical technology. A fluorometer generates the wavelength of light required toexcite the analyte of interest, it selectively transmits the wavelength of light emitted, then it measures the intensity of the emitted light. The emitted light is proportional to the concentration of the analyte being measured.
