Sigma precision thread headspace gas chromatography with high quality

Propane is a lipophilic gas, which means that, in the case of a long exposure to propane and a death by anoxia, a high concentration in fat tissues, brain and kidney should be detected. On the contrary, after a short exposure to propane subsequent to a propane outburst, it is more likely to find higher concentrations in lungs than in fat tissue or brain.

Solid-Phase Microextraction Gas Chromatography Mass Spectrometry (HS-SPME-GC-MS/MS) Method for the Determination of Tributyltin in Sediment: Validation according to EU Directive Requirement. SM Anal Bioanal Technique. 2017; 2(1): 1007.

Headspace GC Our solvents for headspace gas chromatography are developed specifically for the analysis of residual solvents in drug substances, excipients, and drug products according to Ph. Eur. and USP. Their high purity is provided by specially designed

Using liquid chromatography principles to control selectivity, SPE provides the sample cleanup, recovery, and concentration necessary for accurate quantitative analysis. Several benefits of SPE include the simplification of a complex sample matrix, along with compound purification and reduced ion suppression or enhancement in mass spectrometry applications.

Shimadzu's proprietary BID and Millipore Sigma's “Watercol” are combined to separate and measure Water in Petrochemical Products with high accuracy and precision. Utilizing HS or Gas/liquid sampling valves, one can easily automate water determination of

A static headspace gas chromatographic method was developed and validated to determine formaldehyde in pharmaceutical excipients after an effective derivatization procedure using acidified ethanol. Diethoxymethane, the derivative of formaldehyde, was then directly analyzed by GC-FID.

tested; the precision, CV was <15% for all the components identified, and the limits of quantification was very low for most of the components, for example, 1.7 ng/g for ethyl

The aim of our study was to present a new headspace-gas chromatography-mass spectrometry (HS-GC-MS) method applicable to the routine determination of hydrogen sulfide (H 2 S) concentrations in biological and gaseous samples. The primary analytical drawback of the GC/MS methods for H 2 S measurement discussed in the literature was the absence of a

The injection precision of a headspace injector can consistently give < 10.0% relative standard deviation (RSD) and frequently gives ⩽ 2.0% RSD, similar to the precision found

The analysis is conducted using headspace (HS) gas chromatography (GC) with flame ionization detector. Using a robot autosampler, the samples are digested in full automation with simulated gastric fluid (1 h at 37°C) under shaking, which frees acetaldehyde loosely bound to matrix compounds.

Aijiren’s Magnetic Precision Screw Metal Cap is 18mm in size, which is very suitable for sealing gas chromatography. This kind of cap is often used in headspace vials, and the center hole with it is very convenient for sampling by autosampler.
