Detection of Urethane in Non-alcoholic Fermented Food [PDF]
E3S Web of Conferences, 2020 Among fermented foods, urethane often appears, which is a “2A” grade carcinogen. There are many types of fermented foods in my country, and the detection methods are not uniform enough, and no specific urethane detection standards have been formed.

Maui-VIA: A User-Friendly Software for Visual Identification, Alignment, Correction, and Quantification of Gas Chromatography–Mass Spectrometry Data [PDF]
Frontiers in Bioengineering and Biotechnology, 2015 A current bottleneck in GC-MS metabolomics is the processing of raw machine data into a final datamatrix that contains the quantities of identified metabolites in each sample. While there are many bioinformatics tools available to aid the initial steps of the process, their use requires both significant technical expertise and a subsequent manual ...

Identification and quantification of polyfunctionalized hopanoids by high temperature gas chromatography–mass spectrometry [PDF]
Organic Geochemistry, 2013 Hopanoids are triterpenoids produced mainly by bacteria, are ubiquitous in the environment, and have many important applications as biological markers. A wide variety of related hopanoid structures exists, many of which are polyfunctionalized. These modifications render the hopanoids too involatile for conventional gas chromatography (GC) separation ...
