Pulsed discharge detectors

PDDs (pulsed discharge detectors) utilize a stable, low-powered, pulsed CD discharge in helium as the ionization source.

Thermal conductivity detector

Our microvolume, dual filament thermal conductivity detectors are stand-alone units optimized for capillary chromatography and enhanced sensitivity at low flow rates.

The venerable TCD-2 has analog controls on the front of the controller for setting performance parameters, while the new TCD-3 features full digital control implemented via a user interface or command console commands.
