Relatively recently CAD (Charged Aerosol Detectors) have become a real alternative
to ELSD detectors for use in the analysis of substrates such as carbohydrates,
lipids, surfactants, amino acids, peptides, steroids and natural products. Like
the ELSD detector, optimal performance requires the CAD to be fed with a supply
of clean dry nitrogen. However, unlike the ELSD a second stream of nitrogen
is used to transfer charge to the (now ‘dry’) analyte particles
that is subsequently transferred to a collector and measured by a electrometer.
Parker domnick hunter’s G2310 Nitrogen generator offers the analytical
chemist the ideal gas supply solution for CAD detectors.
