Static Headspace-Gas Chromatography: Theory and Practice has long been the only reference to provide in-depth coverage of this method of analysis. The Second Edition has been thoroughly updated to reflect the most recent developments and practices, and also includes coverage of solid-phase microextraction (SPME) and the purge-and-trap technique.

For accurate results and to maintain chromatography consumables, sample preparation is a highly important step to include in chromatography analysis. The fundamentals of sample preparation can be summarized by using filtration (syringe filters, filter vials and centrifuge filters), understanding extraction methods such as solid phase and liquid-liquid extraction, as well as protein crash and

Headspace Vials Caps for Headspace Gas Chromatography Applications Headspace gas chromatography requires headspace vials and caps because they can withstand the pressure from the gas. Chrom Tech has a wide selection of high-quality crimp and screw thread headspace vials available in clear or amber glass with associated 18-and 20-mm headspace closures.

headspace gas was 1 mL. The carrier gas was nitrogen at a flow rate of 5 mL/min. (V) Identification and Quantification of Ethephon After sample preparation as described above, 1 mL of headspace gas was injected into the GC device. Ethephon was tentatively

1999/10/22 · Chromatography was initiated with a non-split injection on a packed column injector at a flow-rate of 6 ml/min of helium as a carrier gas. A minimum flow-rate of 0.2 ml was received from the GC packed column injector to prevent the sample from backing up into the injector lines during injections from the headspace autosampler.

Our gas chromatography (GC) solutions are designed to be customized so that they can fit any laboratory workflow. From Thermo Scientific Instant Connect injector and detector modules, to our performance-leading Thermo Scientific mass spectrometers, we offer the largest portfolio of GC solutions that enable you to innovate as well as customize your gas chromatography applications.
