Absorption Measurements in Microfluidic Devices Using Ring-Down Spectroscopy
When monitoring separation events in microfluidic devices, one frequently needs to detect small amounts of analyte in picolitre sized volumes with a time response of milliseconds. Fluorescence detection is typically the ...
Chemical Sensing Using Fiber Cavity Ring-Down Spectroscopy
Waveguide-based cavity ring-down spectroscopy (CRD) can be used for quantitative measurements of chemical concentrations in small amounts of liquid, in gases or in films. The change in ring-down time can be correlated to ...
