Gas Chromatography with an Electron Capture Detector, GC-ECD, is a technique commonly used in the pharmaceutical, forensic and environmental markets. The Electron Capture Detector, invented by Scientist James Lovelock in 1957, is used to detect molecules and atoms in a gas via electron capture ionization, to detect electron-absorbing. VICI PDDs (pulsed discharge detectors) utilize a stable, low powered, pulsed DC discharge in helium as an ionization source. Eluants from the column, flowing counter to the flow of helium from the discharge zone, are ionized by photons from the helium discharge Thermo Scientific Dionex absorbance detector and an electrochemical detector is a versatile and powerful analytical instrument. 1.2 Detection Modes The Dionex ED50A provides two major forms of electrochemical detection: DC amperometry and integrated amperometry. Pulsed amperometry is a form of integrated amperometry
