Programmable Cool On-Column Inlet

The temperature programmable cool on-column (COC) inlet for 8890, 8850, 8860, and 7890B gas chromatography systems allows direct injection of a GC sample onto a cool capillary column. This ensures quantitative sample transfer without thermal degradation of analytes.The COC inlet offers high accuracy and reproducibility. It is ideal for thermally labile or unstable compounds or for GC samples containing components with large boiling-point differences that may experience discrimination when injected into a hot inlet.
