In last years, analytical approaches employing gas chromatography coupled to time-of-flight mass spectrometry (GC TOF-MS) proved to be a useful tool in assessment of quality and safety of food, beverages and water. But only recently, at the end of 2007, new TOF MS detector specially designed for high-throughput of samples (TruTOF), has been introduced. In this work the evaluations of such instrumentation is performed in analysis of fatty acid esters, pesticide residues and polybrominated compounds. The ionization mode (EI, CI) and GC-MS settings has been optimized in order to obtain fast and reliable analytical methods for routine control of purified extracts of different food-stuffs and enviro-matrices.

Moreover, GC x GC coupled to TOF-MS has been applied for authentication of  beverages based on the volatile organic compounds profile. 

Appraisal of mentioned techniques with respect to the cost and time demands was also done.
