CHEMICAL SENSOR FOR ASSAY OF PROPANONE-2 IN AIR, DEVICE FOR ASSAY OF PROPANONE-2 IN EXPIRED AIR AND A METHOD OF HYPERKETONEMIA DIAGNOSIS

摘要

FIELD: analytical chemistry and biochemistry, medicine. SUBSTANCE: propanone-2 is determined using chemical sensor that has fluoro-containing copolymer of polyvinylidene fluoridehexafluoropropylene as a sensitive surface and piezoelectric resonator AT-slice (oscillation frequency is 20 MHz) as physical-chemical transformer that is connected with sensitive surface. Mass of electrode sensitive resonator surface is 50-100 mcg, volume of reaction cell is 0.4 cm³. Device and method can be used in medicine for hyperketonemia diagnosis. EFFECT: improved method of analysis. 3 cl, 12 tbl, 2 dwg
