Mass Spectroscopy Mass Spectrometry is an analytical spectroscopic tool primarily concerned with the separation of molecular (and atomic) species according to their mass. Mass Spectrometry has a number of uses for example geologists use it to date rocks, pharmaceutical companies make use of mass ...

Mass spectrometry can be orientated toward the identification and classification of microorganisms by using protein ‘fingerprints’ (characteristic protein expression patterns that are stored and used as specific biomarker proteins for cross-matching). The utilization of long-standing technology is based on...

Mass spectroscopy, on the other hand, is one of the most information - rich detectors. It requires only micrograms of sample, but it provides data for both 156 INSTRUMENTATION 157 (a) the qualitative identifi cation of unknown compounds (structure, elemental composition, and molecular weight) ...
The concept of metabolite profiling has been around for decades, but technical innovations are now enabling it to be carried out on a large scale with respect to the number of both metabolites measured and experiments carried out. Here we provide a detai
