A new study from the University of Nottingham has looked at how the anesthetic gases breathed out by animal patients are ...
In this article, we take a look at what gas chromatography is, how it works and how to interpret output data. Its combination with mass spectrometry and the use of multiple dimensions are considered.
LCGC International spoke to Phil Marriott and Humberto Bizzo about a recent paper they published identifying the incorrect use of retention indices in gas chromatography and how this problem can be ...
The retention time of the vapor is determined with a flame ionization detector (FID). Varying the flow rate, vapor probe molecule, column conditions or temperature reveals a wide range of bulk and ...
Spread the loveRetention time is an important parameter in chemical analysis, particularly in chromatography, as it enables the identification and quantification of compounds based on their unique ...
The EPA is proposing strict new limits on PFAS in drinking water. Consumer Reports' tests suggest many Americans' drinking water night have PFAS above the proposed federal levels.
Summary Gas chromatography is a chromatographic method that uses gas as a mobile phase. The sample flows through the gas system and is gasified before finally entering a chromatographic column filled ...
Solid adsorbent gas chromatography (GC) columns, such as porous layer open tubular (PLOT) columns, are the best option for GC analysis of C1–C5 hydrocarbons, but water can affect retention and ...
The stationary phase contains either a solid adsorbent, which is known as gas-solid chromatography or a liquid on inert support called gas-liquid chromatography. On completion of the analysis, GC ...
