Mass spectrometry, with an inductively coupled plasma, of inorganic trace impurities in ultrapure water

The final result of investigations of the mass spectrometer with an inductively coupled plasma for analysis of inorganic trace impurities in ultrapure water was the development of instrumental-methodological techniques for increasing the efficiency and reliability of the recording process. This made it possible to choose internal calibration standards and criteria for changing the calibration coefficients. The research instrumentation complex, developed at the All-Union Scientific-Research Institute of Technical and Physical Apparatus, is suitable for quantitative analysis of the elemental content of trace impurities in water with the indicated analytic characteristics for the relative method of measurement according to internal calibration standards. A further improvement of the research apparatus is lower transmission losses which result from the effect of the edge fields according to the constant and variable components, with the aid of a nonuniform standing wave of voltage applied to the mass analyzer as well as the detection limit obtained with the aid of an ion-trap-type detector. The preliminary results show that these techniques make it possible to improve transmission by up to a factor of 30 and to work with a resolution of 100M, as well as to decrease the detection limits by a factor of 10.

In conclusion, we thank S. S. Grazhulen and Yu. I. Popandopulo (Institute of Applied and Theoretical Mechanics of the Russian Academy of Sciences) for collaboration and assistance in performing the control measurements of the impurity content in the samples on the VG Elemental PQ2 mass spectrometer with an inductively coupled plasma, S. G. Galaktionov and A. L. Makarov (All Union Scientific-Research Institute of Chemical Technology) for providing the samples, and A. A. Sysoev (Moscow Engineering Institute) for a helpful discussion of the results.
