Annotation
Based on the results of the conducted studies, a method for ensuring the selectivity of acetone detection has been proposed using semiconductor sensors integrated into a single unit containing catalysts with sufficient activity toward the analyzed mixture. The absolute and relative errors and variation of the analytical signal were determined in accordance with the parameters specified by the State Standard GOST 13320-81 and were found not to exceed the established limits. At a confidence level of 0.95, the total reduced error over the measured concentration range fully complies with the requirements of the State Standard GOST 52033-2003 for instruments of this type and does not exceed ±1.5%.
