METHOD TO MANUFACTURE STANDARD SAMPLES OF ATMOSPHERIC AEROSOLS LOADED ON A FILTER Russian patent published in 2004 - IPC

FIELD: analytical chemistry.

SUBSTANCE: the invention is dealt with analytical chemistry, in particular, with methods to manufacture synthetic standard samples, composition of which imitates the structure of atmospheric aerosols, loaded on a filter and may be used in a quantitative chemical analysis of structure of atmospheric aerosols for elaboration of a calibration equation and verification of correctness of the analysis results. The method to manufacture of synthetic standard samples of the atmospheric aerosols loaded on a filter provides for preparation of a methyl cellulose film containing defined elements. Then they die-stamp individual copies out of the film. Selected in the given ratio shares of the fine-grained powder containing defined elements and the dry methyl cellulose are mixed till production of a one-color mixture and it is filled with distilled water heated to the temperature of 70-80°С. The mixture is carefully agitated and kept at ambient temperature for 2 hours agitating it each 30 minutes. The method allows to increase accuracy of the analysis of atmospheric aerosols by approximation o the physico-chemical characteristics of the samples of comparison and the real probes of the aerosols loaded on the filter.

EFFECT: the invention allows to increase accuracy of the analysis of atmospheric aerosols loaded on a filter.
