Evaluated the retention of essential aromatic components in fresh herb using Headspace analysis, gas chromatography and mass spectrometry. Investigating various methods to determine which best retained "fresh" quality parameters and extended shelf life for retail and storage.

3.9.3 Headspace gas chromatography. Headspace GC is a sampling technique that involves the indirect determination of volatile constituents in liquid or solid samples by analysing the vapour phase that is in thermodynamic equilibrium with the sample in a closed system [149, 150]. It is used predominantly for the determination of volatile constituents present in trace concentrations.

Hydrogen 5.0. Hydrogen is an extremely flammable gas that is lighter than air. This high purity hydrogen is available as a compressed gas or cryogenic liquid in a range of sizes. Hydrogen 5.0 is inexpensive and abundant compared with Helium 5.0, which has led to it gaining in popularity in laboratories as a carrier gas.

Feb 15, 2011 · This process induces a reaction that converted all target compounds to their respective trimethylsilyl derivatives to increase their suitability for analysis using gas chromatography (GC). Following the derivatization, anthracene d 10 was added to each sample as an instrument internal standard (IS) prior to GC analysis.

Description Headspace vials from Aijiren Technology, Inc with high quality and favorable price. Zhejiang Aijiren is a manufacturer of Laboratory consumables. We supply autosampler vials, septa and caps at factory price. 8mm Screw Thread Headspace Vials are often used in Shimadzu, Spectral Physics, Varian, and other autosamplers.

In the world of volatiles analysis, Headspace Gas Chromatography Mass Spectrometry (HGCMS) supersedes its competitors through the direct injection of volatiles. Highly volatile and low boiling compounds are preferentially evolved from a sample into the headspace gas during gentle heating. This headspace is collected within a hermetically sealed vial and directly injected into the GC instrument.
