Introduction to the Pulsed Discharge Detector (PDD) for gas chromatography



Date: 09:00:00 - Apr 26 2022
Speakers: Peter Nastold
Moderators: Tom Lynch CChem FRSC

Gas chromatography (GC) is one of the most important analytical technologies, but its power relies on the availability of sensitive detectors, able to quantify a range of analytes as extensive as possible. This webinar will show the Pulsed Discharge Detector (PDD) to meet this demand by combining true universality in detection, with a broad dynamic range, and sensitivity down to the ppm and ppb range.

After setting the PDD in relation to other detectors for GC, generally regarded as universal, a brief explanation of its physical basics will make its capabilities understandable. Different operation modes, providing selectivity where required, are shown as well as how a PDD can replace an Electron Capture Detector and help to eliminate radioactive material from the lab.

Different models of the PDD are introduced, adapted to a range of widely used GC systems. Together with application examples from a broad field of analytical tasks, the webinar will show how the potential of this detector can be easily applied and made productive in every GC laboratory.
