As a general recommendation for HILIC standard methods, select a 100 or 150mm long column, packed with 3 - 5µm particles and with a 4.6mm id, if using UV detection. If HILIC is coupled to MS or CAD detection, use a smaller column, e.g. 100 x 2.1mm or 50 x 2.1mm, packed with 3-5µm particles. 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 how can i get a background check on myself
