Microbiology is the study of microorganisms including protists, prokaryotes, fungi, and, often, viruses. Microorganisms are a useful research tool as genetic vectors and, in immunology, for antibiotic susceptibility testing, cellular biology and genetics.
Chromatography Vials. Designed to use separating organic and inorganic compounds for analysis, chromatography vials come in different finishes to guarantee chemical compatibility. Autosampler compatible closures come in different colors, sizes, and septa materials. Offered with a write-on patch, possible identification errors are eliminated.
The GC vial liquid sampler from Mechatest has unique needle-in-needle design, it uses extraction needles of 0.6 or 1.2mm diameter and enables direct vial sampling of volumes of either 2, 10 or 20 ml. These are the smallest vial sizes typically found in GC autosamplers and is therefore arguably the best solution for taking samples, specifically

Gas chromatography (GC) is a chromatographic technique used for the rapid separation of volatile compounds using an inert carrier gas (mobile phase). The mobile phase drives the gaseous compounds through the heated column which is coated with a solid or liquid stationary phase.

Based on multiple headspace extraction gas chromatography (MHE-GC), the methanol released from the liquid sample of interest in a closed sample vial was determined in a stepwise fashion. A theoretical model was derived to establish the relationship between the diffusion coefficient and the GC signals from MHE-GC measurements.
The methods are based on gas chromatography-mass spectrometry (GC-MS) of the derivatised analyte and on high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) of native acrylamide. Isotope dilution with isotopically labelled acrylamide was an integral part of both methods.
