Aug 7, 2018 · Abstract. Gas Chromatography-Headspace (GC-HS) is a commonly used analytical technique in research and industrial laboratories for quality control as well as identification and quantitation of

Thermo Scientific™ 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. Headspace vials, septum, and caps can be purchased in various quantities separately or together as convenience kits to fit your laboratory needs. Product Overview

Basics of Static Headspace Analysis: Part 1. When it comes to determining the level of volatile species in solid, liquid or gas samples, one of the more popular techniques is Static Headspace analysis. Simply stated, Headspace is the gas phase or vapor portion of a sample in a sealed chromatography vial. Consumer products.

Aijiren headspace vials come in both flat bottom and round bottom styles for use in a wide variety of headspace instrument platforms. Headspace screw caps and crimp caps come in a variety of styles and materials including aluminum, bimetal, and steel; headspace cap septa are available in PTFE/silicone, molded PTFE/butyl, and high-temperature

Headspace is used to analyze volatile compounds in liquid and solid samples that cannot be injected directly into a gas chromatograph (GC). Examples would be creams and lotions, blood, soil, electronic components, and polymers. Headspace sampling can accommodate virtually any matrix. How does headspace sampling work?

Headspace sampling is a type of sample introduction technique for gas chromatography (GC) and gas chromatography-mass spectrometry (GC/MS). For headspace techniques, the gas layer, or the headspace above the sample in a vial, is analyzed as opposed to withdrawing a volume from within the sample layer (Figure 1).

Apr 18, 2006 · STATIC HEADSPACE-GAS CHROMATOGRAPHY. THE ONLY REFERENCE TO PROVIDE BOTH CURRENT AND THOROUGH COVERAGE OF THIS IMPORTANT ANALYTICAL TECHNIQUE. Static headspace-gas chromatography (HS-GC) is an indispensable technique for analyzing volatile organic compounds, enabling the analyst to assay a variety of sample matrices while avoiding the costly and time-consuming preparation involved with

In this evaluation, the utility of DMSO headspace grade solvent was evaluated for use in the SH-GC analysis of OVIs. The purity of the headspace solvent was evaluated by preparing sample blanks using headspace and alternative grades of DMSO. The retention times of peaks present in the blanks were then compared to an OVI standard prepared in
