Abstract

The study presents a comparative assessment of a composite heat insulation material based on evacuated glass microspheres and a polymeric silicone matrix with common heat insulation materials used as a heat insulating layer for microfluidic gas chromatographic columns as part of a gas microchromatograph. It was shown that the developed heat insulation material is characterized by an operating temperature of up to 350°C and a thermal conductivity coefficient of 0.045 W/(m·K). It has been experimentally established that the use of this material as part of a thermostat of a gas microchromatograph allows to reduce energy consumption by 15-25%, increase the resolution of chromatographic peaks by 5-10%, and increase the stability of chromatographic parameters during the contact of the temperature control zones of various units of the microchromatograph by 2-3 times compared with traditional heat insulation materials. The results obtained allow to recommend the studied material for the improvement of microdevices used in gas chromatographic analysis.
