Gas chromatography–mass spectrometry analyses of encapsulated stable perovskite solar cells
Perovskite decomposition in detail Solar cells are subject to heating when operating in sunlight, and the organic components of hybrid perovskite solar cells, especially the commonly used methylammonium cation, can undergo thermal decomposition ...

Auto-deconvolution and molecular networking of gas chromatography–mass spectrometry data
We engineered a machine learning approach, MSHub, to enable auto-deconvolution of gas chromatography–mass spectrometry (GC–MS) data. We then designed workflows to enable the community to store, process, share, annotate, compare and perform molecular ...

Gas chromatography-mass spectrometry in the taxonomy of Miscanthus
Chemotaxonomy as a system approach deals with intra- and interspecific polymorphism of a group of taxa in order to clarify their taxonomic positions or to select material for selection or introduction.

Pipecolic Acid Quantification Using Gas Chromatography-coupled Mass Spectrometry
Pipecolic acid (Pip), a non-proteinacious product of lysine catabolism, is an important regulator of immunity in plants and humans alike. For instance, Pip accumulation is associated with the genetic disorder Zellweger syndrome, chronic liver diseases ...

Microbial Metabolomics with Gas Chromatography/Mass Spectrometry [PDF]
An analytical method was set up suitable for the analysis of microbial metabolomes, consisting of an oximation and silylation derivatization reaction and subsequent analysis by gas chromatography coupled to mass spectrometry. Microbial matrixes contain many compounds that potentially interfere with either the derivatization procedure or analysis, such ...
