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.

Basics & Fundamentals: Gas Chromatography. Introduction . Gas chromatography (GC) is an analytical methodology, which was devised by Nobel Laureate, Martin, et al. in 1952. More than 60 years after the award, GC systems are widely commercialized and used in various industries, capable of both of quantitation and qualifcation.

Headspace Gas Chromatography. Headspace gas chromatography connected to an FID and/or an MS detector can be applied to obtain better precision and accuracy for the quantitative analysis of volatile organic compounds (VOCs) in bio-oils including light aldehydes and ketones, ethers, esters, alcohols, carboxylic acids and aromatic compounds [32,49].

Chromatography Thermo Scientific™ 20 mm Headspace Vials, Septum, and Caps Headspace vials are available in clear or amber glass with a round or flat base, a crimp seal with a beveled or square edge finish, or with a screw-thread finish.

I cap a headspace vial and fill it with a calibration gas by inserting two needles into the septum. One needle is long and reaches to the bottom of the vial and through this needle the gas is flowing. A second short needle is inserted in the septum to allow the gas to escape and flow to occur.
