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.
SpectralWorks Limited (SpectralWorks) is now the exclusive distributor for IonSense Corporations’ (IonSense) DART ionization sources, and consumables.
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.
