The Eclipse 4660 Purge-and-Trap Sample Concentrator processes samples for analysis of volatile organic compounds (VOCs) by gas chromatography (GC) or gas chromatography/mass spectrometry (GC/MS). Innovative, patented components within the Eclipse significantly improve sample processing steps of the purge-and-trap technique.
A key technology is the built-in Cyclone Water Management system that removes water during the thermal desorb step. The high efficiency of water removal allows analysis of polar compounds such as alcohols, ethers, and ketones without interference from water. Degradation of chromatographic columns and maintenance of the GC or GC/MS are also minimized.
