GC-HS

Gas chromatography with headspace sampling (GC-HS) is a powerful analytical technique used to separate and quantify volatile organic compounds (VOCs) in various sample matrices. It works by heating a sample in a sealed vial to release the volatile components into the headspace, which is then sampled and injected into a gas chromatograph. The GC separates the individual compounds based on their boiling points and affinities for the stationary phase of the column, allowing for precise identification and quantification using detectors such as FID or MS. This technique streamlines sample preparation, often eliminating the need for complex extraction procedures, and is compatible with leading GC systems from manufacturers like Agilent, Thermo Fisher Scientific, and PerkinElmer.

This technique streamlines sample preparation, often eliminating the need for complex extraction procedures, and is compatible with leading GC systems from manufacturers like Agilent, Thermo Fisher Scientific, and PerkinElmer. GC-HS supports diverse workflows for environmental monitoring, food and beverage analysis, pharmaceuticals, forensics, and materials testing. Common applications of GC-HS include analyzing residual solvents in pharmaceuticals, determining aroma profiles in food and beverages, measuring volatile emissions from polymers, and detecting volatile organic pollutants in environmental samples. The technique is valuable in both qualitative and quantitative analyses, offering high sensitivity and selectivity for identifying and measuring trace levels of VOCs. By integrating headspace sampling with gas chromatography, researchers can gain valuable insights into the composition and properties of volatile compounds in a wide range of applications, facilitating improved quality control, product development, and environmental monitoring. ALT carries a wide selection of pre-owned, refurbished GC-headspace systems. Every unit includes a standard 90-day warranty, with the option to upgrade to a three-year warranty, plus ALT's lifetime support for as long as you own the equipment. Refurbished GC-headspace systems from ALT typically cost 50%-80% less than buying new, making it easier for labs to get the equipment they need without straining their budget. - Less
