Near infrared spectroscopic techniques have always played an important role in the monitoring of chemical processes. In particular the use of near infrared absorption spectroscopy is used as a standard laboratory method of determining the chemicals present within a given sample. Conventional near IR spectroscopy generally does not have a high sensitivity for trace chemical detection, or are not well suited for on-line, real-time, reaction monitoring of liquid species at very low concentrations and for bio-molecule detection. With the advent of lab-on-a-chip systems and micro-fluidic chemistry there is an increasing requirement for detection methods in which the sample is not removed from the system.
