The makeup gas of the restrictors was set at a constant flow rate of 2 mL/min, not a constant pressure of 3.8 psi as recommended by the manufacturer. Helium was used as the carrier gas and makeup gas. All gases were of ultrahigh purity. All samples were analyzed using the HS-GC-FID-MS described above with an HS oven temperature of 50°C.
Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture. [1]
liquid matrices. The samples are placed in HS crimp-top glass vials and heated at a set temperature for a fixed amount of time. The instru-ment is built so that the vial can be equilibrated and shaken in the oven precisely with a 0.1 C accuracy. The best feature of this add-on is that it can be directly attached the gas chromatograph (GC) inlet via
ChromineX™ is a platform that IT Tech has created for chromatography products from those potential but low-profile manufacturers all around the world with one purpose, that is to bring down customer investment without jeopardizing the result quality of their analytical work.
Jan 26, 2010 · lkochraney wrote: Naturally, choice is up to the end user and instrument requirements. Some instruments require magnetic seals, and unless there has been a recent introduction of a magnetic screw cap vial in a 1-2mL volume, crimp vials would be required.
Any ideas as to what could cause a static headspace injection to produce peak areas roughly 60-80% higher than the other injections in the series? For example, in a 6-injection series of a std. solution containing 12 residual solvents, 5 out of the 6 injections will be right on top of each other with %RSDs <5 for all analytes.

Headspace single drop microextraction coupled to gas chromatography–mass spectrometry yielded a simple, fast and virtually solventless analytical protocol used for the headspace analysis of aqueous samples contaminated with
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 volatile
Static headspace gas chromatography (GC) , due to its low sample matrix interference and high sensitivity, has been the preferred methodology for detecting volatile compounds in drug substances and drug products . However, carryover generally occurs for TEA in headspace GC . DMSO, due to its low vapor pressure and high solubility for organic
May 19, 2020 · Headspace gas chromatography, coupled to flame ionization detection (GC-FID) analysis of blood alcohol concentration is a routine analysis carried out in forensic laboratories.
The Headspace Vial are used in GC to heat the sample until the concentration of the liquid and gas phases are in equilibrium. Samples are then taken from the gas phase (headspace) for analysis. Chrominex™ Headspace Vials are available in Clear or Amber borosilicate glass with Crimp or Screw thread top.
Comprehensive 2D GC coupled to time‐of‐flight mass spectrometry was applied for the characterization of the particulate phase of mainstream tobacco smoke particulate.
