Apparatus and methods for improving fluorescence detectors

摘要

A method and apparatus are disclosed for the improving the sensitivity of fluorescent detectors, especially UV fluorescent detectors using a light reaction cell including a reaction chamber having an optically smooth, highly reflective interior surface. The chamber can also include an insert that imparts either or both optically smooth and high reflectivity to the chamber. Increased interior surface smoothness and reflectivity significantly improves sensitivity and detection limits making ppb measurements routine.
