Gases for Electron-Capture Detection
Q: What do you advise using as gases with electron-capture detection (ECD) for gas chromatography? Would it be better to purchase higher quality gases or to place an oxygen trap between the gas bottle and the detector? Which setup would be the most cost-effective?
A:John Hinshaw: The best choice is to use both high quality gases and an oxygen trap. A high-purity, high-quality gas cylinder will contain absolute minimum amounts of contaminants such as hydrocarbons, air, water, and other chemicals that could interfere with the electron-capture detector’s operation.
