The widespread use of formic acid and/or ammonium acetate, together with either methanol or acetonitrile, is in fact one practical reason to also use these buffers and solvents in our fingerprint applications, although no separation column is used. The main argument is that control of pH and ionic strength is obligatory for the control of ionization, especially with ESI-MS.The effects of different buffers (25 mM formic acid and 50 mM ammonium acetate) and different solvents (methanol and acetonitrile), and the most important mass spectro-metric parameters on the fingerprint spectra of crude oils were studied and published in a separate method paper [10].

Anonymous fingerprinting applications of PTR-MS, that is, where the analysis is not concerned with identifying specific VOCs, but instead merely uses the mass spectral peaks as some form of information, have been successfully applied in several studies of food quality and control. A few examples have already been met earlier in this chapter in a different context, but in this section the emphasis is on food classification. A particularly interesting and perhaps unexpected application of this relates to determining the geographical origin of food and drink products. 

In conclusion RAIRS, which affords high spectral resolution, is a very versatile nondestructive optical technique which does not depend on a vacuum environment. Vibrational spectra also serve as characteristic fingerprints for adsorbate molecules, adsorption configurations, and structures on metallic and dielectric substrates. Extension to include dielectric substrates opened new fields of application in polymer and biochemical research. 

When evaluating gas concentrations in practical applications, a reterence spectrum is least squares fitted to the received absorption spectrum. This im proves the system accuracy, since the spectral fingerprint over the whole scanning range contributes to the result.- ...

A recent application of this type of fluid is assistance in the removal of ingested salt spray from jet aircraft compressors and the neutralisation of corrosive effects. Other types of water-displacing fluids are claimed to have fingerprint neutralising properties or to be suitable for use on electrical equipment. Some oil-type materials serve temporarily as engine lubricants and contain suitable inhibitors to combat the corrosive products of combustion encountered in gasoline engines.

To detect adulteration of wine. Bums et al. (2002) found that the ratios of acetylated to p-coumaroylated conjugates of nine characteristic anthocyanins served as useful parameters to determine grape cultivars for a type of wine. Our laboratory utilized mid-infrared spectroscopy combined with multivariate analysis to provide spectral signature profiles that allowed the chemically based classification of antho-cyanin-containing fruits juices and produced distinctive and reproducible chemical fingerprints, making it possible to discriminate different juices. " This new application of ATR-FTIR to detect adulteration in anthocyanin-containing juices and foods may be an effective and efficient method for manufacturers to assure product quality and authenticity.
