Abstract: FIELD: analytical chemistry. SUBSTANCE: method provides testing of the sample of trimethylgallium - 0.00067-0.0540 grams - placed into the first reaction chamber where the sample is decomposed by high-voltage spark which has parameters C=1500 pF, L=3mcH, V=15 kV during 1.5-2 minutes. Then decay products of trimethylgallium are blown through by oxygen at rate of 2ml/min into the second reaction chamber where ozone is produced under action of oxygen high-voltage spark. Ozone oxidize decay products and sulphur-containing organic compositions correspondingly to sulphur trioxide during 8-10 minutes. Trioxide of sulphur is blown through quartz trap by oxygen stream into bubbler filled with absorbing 0.002 M carbonic sodium solution, where sulphur trioxide is oxidized till reaching sulfate-anion. The latter is determined by method of ion-chromatography when carbonic sodium solution is used eluate. Contents of sulphur in trimethylgallium is judged from sulfate-anion content.

Pref. gas is compressed by the working member (7)moving in each compression chamber (6) and is fed to the consuming unit, pref. an injector or nozzle (8) entering a tool cavity, via an outlet line (18) with a one-way valve (12). Gas may be stored at an accumulator (9) between the compression chamber (6) and tool cavity. Several working chambers (6) may be used, one behind the other and interconnected via channels. Each working chamber (6) may be of a different size and water-based coolers are located between each chamber (6). A prescribed gas pressure is held in the chambers (6) prior to tool (10,11) closure by air flow via a line (1a) with a control valve (2). Pressure remains constant while the tool is closed and during tool opening falls slowly in each chamber (6). The compression chambers (6) and working members (7) may be integrated into the tool parts (10,11) or can be mounted separately on the latter (10,11).
