“…The biosamples preserved in this way can be sent to stationary laboratories without special requirements for transportation conditions, for example, in postal envelopes. Earlier, a technology was proposed for the determination of OPNA adducts with albumin in the dried spots of blood plasma [18]. The approach based on the use of dried blood spots is interesting primarily due to the easy stabilization of the test sample, which makes it possible to avoid degradation in the course of storage and transportation.…”

The areas of application of modern bioanalytical chromatography-mass spectrometry are so extensive that any attempt to systematize them becomes subjective. It would be more correct to say that there is no such area of biology and medicine where chromatography-mass spectrometry would not find application. This article focuses on the areas of application of this technique that are either relatively new or insufficiently covered in recent reviews. State-of-the-art bioanalytical techniques have become multitargeted in terms of analytes and standardized in terms of matrices. The ability to detect trace concentrations of analytes in the presence of a huge number of biomatrix macrocomponents using chromatography-mass spectrometry is especially important for bioanalytical chemistry. In the target-oriented determination of persistent organic pollutants by chromatography-mass spectrometry, the main problem is the expansion of the list of analytes, including isomers. In the detection of exposures to unstable toxicants, the fragmented adducts of xenobiotics with biomolecules become target biomarkers along with hydrolytic metabolites. The exposome reflects the general exposure of a human being to total xenobiotics and the metabolic status reflects the physiological state of the body. Chromatography-mass spectrometry is a key technique in metabolomics. Metabolomics is currently used to solve the problems of clinical diagnostics and anti-doping control. Biological sample preparation procedures for instrumental analysis are being simplified and developed toward increasing versatility. Proteomic technologies with the use of various versions of mass spectrometry have found application in the development of new methods for diagnosing coronavirus infections.

“…Salting out or freezing in acetonitrile is often used in sample preparation for survey GC-MS and HPLC-MS n analysis. In this case, the losses of even polar analytes such as alkylmethylphosphonic acids were avoided [90].…”
