The distinctive components between tomato juice products could be searched by capture of aromatic components with a headspace sampler and an non-targeted multivariate analysis by AnalyzerPro. An objective evaluation of the influence of differences in the types of raw materials/production process on aromatic components is possible by this approach.
The composition of volatiles from freshly ground roast-ed coffee is complex, with hundreds of chemical compounds contributing to the aroma. Head-space solid-phase micro-extraction was used to sample volatiles from five different coffees for analysis by GC-MS. Chemometric analysis revealed specific differences between coffees from different origins and different preparations.

Traditionally, mass spectrometers commonly available to open access core facility users are low resolution GC-EIMS or LC-ESIMS with single quadrupole mass filters.
Metabolic profiling of breath analysis involves processing, alignment, scaling and clustering of thousands of features ex-tracted from Gas Chromatography Mass spectrometry (GC-MS) data from hundreds of participants.
