The Potential of Volatile Organic Compounds. Study of VOCs in Biological Matrices by GC-MS & Gas-Sensors

The analysis of VOCs emanating from biological samples appears as one of the most promising approaches in metabolomics for the study of diseases. The presence of volatile markers has been explored in exhaled breath, urine, blood, saliva, feces, human semen and cell cultures. Detection and quantification of VOCs are carried out by gas chromatograph-mass spectrometer system (GC-MS) and/or gas sensors.
