Introduction. Headspace (HS) coupled with gas chromatography (GC) provides quantitative and qualitative information about the volatile components that are present in complex sample matrices. The Aijiren Headspace Sampler is part of Aijiren’s line of gas chromatography products.

2013/11/8 · Headspace gas chromatography is a combination of a sampling technique (headspace (HS)) with a separation technique (gas chromatography (GC)). It allows the analysis of volatile organic compounds (VOCs) in complex matrices without extensive sample preparation and it avoids the problems associated with the injection of dirty samples in a gas chromatograph.

Headspace-Gas Chromatography Headspace-GC analysis was performed according to the method described by De Maria et al. (2). A coffee bean sample of 0.5g was roasted at 280 C for 14 minutes in a vacuum-sealed test tube. 4mL of the resulting gaseous

2020/11/26 · The volatile compounds were identified using headspace solid-phase microextraction with gas chromatography-mass spectrometry, and the samples were treated with high-performance liquid chromatography for the quantification of ca eine, chlorogenic acid, and trigonelline.

2021/6/1 · The headspace gas chromatography (HS-GC-FID/FID) method for the determination of ethanol in beers, wines and soft drinks has been evaluated and fully validated. The described technique is sensitive and precise with a sufficiently wide range (0.01–20.0%), therefore it can be applied for quality control of beverages in accordance to both, EU standards and BJCP recommendation.

SupraSolv ® solvents are ideal for all gas chromatography lab applications and prepared for use with various detector systems (ECD, FID & MS) or headspace sampling. Uvasol ® solvents are specially designed for applications that demand solvents of the highest spectral purity and are widely used in IR, UV and fluorescence spectroscopy.
