CHROMtalks - Optimizing the Inlet-to-Column Transition in Gas Chromatography

Most consider the inlet as the weakest part of a gas chromatograph. It is through the sample transport process that most issues arise. Included in the sum of possible problematic phenomena is the transition from the inlet to the column. It is here that the (hopefully) vaporized sample moves from the inlet to the column in a predictable, representative, and repeatable way. Yet this is not always the case. This talk will cover the key transport phenomena, how they can become problematic, the variables that contribute to the problem, and best practices that can minimize variability.
