WebIf 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. Reduce column length only after having considered sample complexity and detector selectivity. For higher separation efficiency and resolution we suggest using either sub 2µm fully porous particles or solid core ... 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.
