    Clarus 600/680 GC User’s Guide The Photoionization Detector (PID) is designed to allow the effluent from a chromatographic column to be ionized by ultraviolet light (provided the ionization potential of the effluent is less than that of the UV source). The current produced by the ion flow is measured by the detector and is proportional to the concentration of the ionized material.
  • Page 62: Npd

    Touch Screen Navigation The nitrogen phosphorus detector (NPD) is a highly specific thermionic detector for organically bound nitrogen and phosphorus. The detector operates by electrically heating a glass bead, that contains an alkali metal, to the point where it emits electrons.

This allows you to amplify the detector signal without getting a large increase in the noise level. Therefore, it provides excellent minimal detection (signal to noise) for all Clarus GC detectors.

    Setting Up the Detectors Matching Detector Signals with Your Integrator The following procedure should be followed if you are operating your detector near the minimal detectable quantity level. This will ensure that the integrator is not filtering the signal coming from the Clarus GC. The purpose of attenuation when an integrator is attached and configured is to assure that the GC output is above the noise level of the integrator.
