Absorbance Spectroscopy, Chemical And Analytical Lab Research Tools, Flow Injection, Gas Chromatography, Liquid Chromatography/HPLC, and Capillary Electrophoresis.
A technology that improves the optical configuration of spectrometers for long path length absorbance measurements for gas and condensed phase. The current technology uses a compact optical cavity with a rotating mirror to control the beam path length as shown in the diagram. For example, HPLC is a technique that could benefit from this unprecedented capability in measuring a wide range of concentrations, i.e., samples containing both ultra-trace as well as relatively high levels could be measured in the same chromatographic run.
