1. Introduction. The seeds, or beans, of the Coffea canephora and Coffea arabica plants are amongst the most highly traded global agricultural commodities. The International Coffee Organisation (ICO) reported that over 9.9 million tons of coffee were produced during the 2019/2020 crop year and over 7.9 million tons of coffee were exported during the 2019 calendar year with global exports

Sep 05, 2015 · GC-MS is a popular and suitable metabolomics method due to its high separation power, reproducible retention times, and selective mass detection. The aim of this study was to establish a reliable untargeted GC-MS method for analyzing firstly a standard compound mixture consisting of 10 compounds representing various compound classes and

Jan 20, 2022 · Detector and column saturations are problematic in comprehensive two-dimensional gas chromatography (GC×GC) data analysis. This limits the application of GC×GC in metabolomics research. To address the problems caused by detector and column saturations, we propose a two-stage data processing strategy that will incorporate a targeted data processing and cleaning approach upstream of the

In the present study, we combined the OSMAC approach with static headspace solid-phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS), high-performance liquid chromatography-high-resolution tandem mass spectrometry (HPLC-HRMS n), and matrix-assisted laser desorption/ionization high-resolution mass spectrometry imaging (MALDI
