ELSD detectors are used in conjunction with HPLC in many situations where the
analytes of interest do not have UV adsorptions and a refractive index detector
cannot be used. Typical applications include the analysis of carbohydrates,
lipids, surfactants, amino acids, peptides, steroids and natural products.
Nitrogen is used to produce a venture-type flow that nebulizes a bulk liquid
phase containing the sample into a fine aerosol mist before the solvent is removed
in the drift tube. Nitrogen is usually preferred over air for safety reasons
Parker domnick hunter’s G2310 Nitrogen generator offers the analytical
chemist the ideal gas supply solution for ELSD detectors.
