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
