In comparison with traditional approaches used in measuring inorganic or organic substances, determining organoelement compounds has its own specifics. First of all, this applies to the use of modern, so-called hybrid methods that combine chromatographic separation and spectral registration of analytes. This publication is devoted to the features of using these methods using the example of measuring the content of the most important groups of organoelement compounds in environmental objects and some biological matrices. The paper provides examples of using a combination of chromatography with mass spectrometry to determine organomercury and organoarsenic compounds. Measuring the content of organotin compounds is considered in more detail. Data on the reference method for measuring the content of organotin compounds in soils and bottom sediments developed at VNIIM, the results of its testing on real objects and certified materials are presented.
