LASER MASS ANALYSER IN THE CONFIGURATION OF A MULTI-PURPOSE TRANSPORTABLE MASS SPECTROMETRIC SYSTEM FOR EXPRESS ENVIRONMENTAL ANALYSIS: APPLICABILITY AND ANALYTICAL LIMITATIONS

摘要

The paper is related generally to the problematic of environmental analysis. Presented are laboratory results, obtained in the process of adaptation for earth application of a miniature laser time-of-flight analyzer, originally created for the purposes of space research on board of a lander. The earth-based version of the instrument is intended to serve as a core analyzer of a universal and multi-purpose transportable mass spectrometric complex for express environmental analysis. The general conclusions about the environmental applicability of the instrument, which analytical performance is qualitative and semi-quantitative, is that the laser spectrometer is acceptable to perform an express mass analysis of environmental samples.
