Sensitive gas chromatography methods have been worked out for evaluation of azocene trace quantities in the air of working and populated area, water, soil, plants and biological material. Chromatographer with thermoionic detector was employed. The lower detection threshold is 2 ng of azocene. The resulting errors is under 20. Other fungicides do not interfere.  相似文献

The article narrates on newly developed techniques for the detection of dichlorpinacolin (DCP) in the working zone air. The study was performed on the chromatograph 'Tsvet 164' equipped with a detector of recombination stability (RCS), using Interton-Super as absorbent with phases SE-30.3% (1), OV-17.3% (II), and Carbowax 1500, 5% (III). The lower threshold for determining DCP in the sample volume was 0.001 mkg, in the air--2.5 mu/m3, and in the water--0.025 m/l. The concentration range in the air: 2.5-40.0 mu/m3 (I,III), 2.5-30 mu/m3 (II); in the water: 0.025-0.4 mu/l (I, III) and 0.025-0.3 mu/l (II). Quantitative assessments were performed through the absolute calibrating technique.  相似文献
