Revision of the End Carbon Chain Concept in the Gas-Liquid Chromatography of Methyl Esters of Unsaturated Fatty AcidsTHE 'end carbon chain', shown to be the key factor in relating the retention time of unsaturated fatty acids of differing chain-length but the same number of double bonds, was...
of the authors' knowledge, breathomics for the specific detection of breast cancer has been reported in a handful of publications investigating classification of patients into healthy versus cancer-diagnosed and summarised by Li et al. in 20209. In these studies, thermal desorption/gas chromatography...

The process development by IFP Energies nouvelles (IFPEN)/ENI/Axens of a Fischer-Tropsch process is described. This development is based on upstream process studies to choose the process scheme, reactor technology and operating conditions, and downstream
In the last decades, thanks to the development of sensitive analytical techniques, such as gas-chromatography/ mass-spectrometry (GC/MS) or ion mobility spectrometry/multicapillary column (IMS/MCC), the clinical util- ity of breath analysis was evaluated for different diseases as, for instance, ...
