Abstract:
Corona Charged Aerosol Detector (CAD) has become standard for many applications in a variety of industries. The Corona is a mass sensitive universal detector for non-volatile and some semi-volatile analytes and response is independent of chemical structure, unlike absorbance, fluorescence, or electrochemical detectors. CAD is an evaporative technique and is based on the charging of aerosol-borne analyte particles by nitrogen gas and corona discharge, with subsequent measurement of the charged analyte particles by a high sensitivity electrometer.
The next-generation Corona ultra detector which supported super-high-speed liquid chromatography (UHPLC) in 2009 was developed. This detector can effectively analyze a wide diversity of chemical structures and important classes of molecules.
