FIELD: chemistry, biotechnology.
SUBSTANCE: invention relates to analytic chemistry with regard to monitoring of environment pollution, control of food products and medications quality, analysis of biological objects. Device contains, first, transparent reservoir with openings for introduction and removal of sample, inside which, at least, one test layer is placed, second, purifying layer, and it also contains additional reservoir with inlet and outlet openings, with possibility to provide in-cut connection with transparent reservoir, purifying layer being placed in additional reservoir. Increase of analysis reliability is achieved.
EFFECT: increase of analysis reliability.
