An Introduction To Headspace Sampling In Gas Chromatography

An Introduction to Headspace Sampling in Gas Chromatography Phase Ratio Other factors that can affect the concentration of an analyte in the headspace phase are the respective volumes of the sample and the headspace in the sealed vial. The concentration of analyte in the sample and the headspace can be expressed respectively as Equations 2 and 3.

HEADSPACE GAS CHROMATOGRAPHY METHOD FOR STUDIES OF REACTION

A vial-in-vial method is used, in which the volatile agent is placed in a small inner vial, and the inner vial is capped with a layer of fabric or film to be tested. The agent permeates from the inner vial into an outer headspace vial. The instrument samples the vapor in the outer vial by sampling it and injecting it into the GC for analysis.

Headspace Volume - an overview | ScienceDirect Topics

The headspace volume must be kept to a minimum to avoid unproductive loss of labeling agent to the gas phase. Heating may be provided thermally or with microwaves. [ 11 C]Carbon dioxide readily traps in solutions of highly reactive organometallic reagents, such as Grignard reagents and alkyllithiums.
