The detector comprises the following main features:
Charged aerosol detection (CAD) method for liquid chromatography for detection of all non-volatile and many semi-volatile analytes
Detection based on measuring charge that is proportional to the amount of analyte, and, for non-volatile analytes, independent of the chemical structure of the analyte
In comparison to UV detection, a chromophore is not required for detection, and in comparison to mass spectrometry, ionization of the analyte is not necessary.
Detection with great sub-nanogram sensitivity and a wide dynamic range
FocusJet™ nebulizer with concentric design for extended low pump flow rate range
Adjustable evaporation temperature for optimization of analyte response and use with a wider range of eluents
VH-D20 detector: Adjustable range for the evaporation temperature
VF-D20 detector: Selectable evaporation temperatures
For data collection, the detector supports the following data collection rate:
VH-D20 detector: Up to 200 Hz
VF-D20 detector: Up to 100 Hz
