Plant, Ecological, Microbiological and Clinical Research Opening new areas to find biomarkers Metabolomics studies based on gas chromatography-mass spectrometry (GC-MS) are well-established and typically employ electron impact (EI) ionisation. Unfortunately, many possible biomarkers detected in these experiments cannot be identified due to the lack of EI reference spectra for a majority of biologically relevant compounds. Hyphenating GC with high resolution TOF-MS technology by soft atmospheric pressure ionisation (APCI) can preserve the molecular ion information and deliver accurate mass...
