Mass spectrometric measurements of halogen-modified 2'-deoxyuridine concentration ratios

A mass spectrometry technique is offered as a tool for quantitative evaluation of halogen-modified deoxyuridine concentration ratios. The direct relationship between concentration ratios of the mixture components and signal intensities is shown. It is found that the mass spectrometric technique is quite suitable for quantitative determination of halogen-modified deoxyuridines, which gives not only concentration ratios of the compounds studied, but also accurate enough quantitative estimates.
