Hilic cad
WebBoth CAD and ELSD are evaporative aerosol detectors able to detect non-volatile and many semi-volatile compounds. But how the particles are detected differs between the two technologies. CAD measures particle charge while ELSD measures the ability of the particle to scatter light. Contact us * Required field WebMS requires expensive instrumentation and maintenance costs can be high. The charged aerosol detector (CAD®) is a mass-sen- sitive detector capable of directly measuring any nonvolatile and many semivolatile analytes.
