The results of using capillary chromatographic columns with different stationary phases were compared to determine the purity of isopropanol obtained by hydrogenation of acetone. The study was performed with columns based on 2-nitroterephthalic acid-modified polyethylene glycol 20М (PEG20М/FFAP), poly(1-trimethylsilyl-1-propyne) (PTMSP032), and trifluoropropyl (25%) methyl silicone elastomer (SKTFT 50Х). The measurement times, asymmetry factors (As) of mixture components, and resolutions (Rs) of the acetone/isopropanol and isopropanol/internal standard pairs of compounds were compared; as a result, the PEG20М/FFAP capillary column was chosen. A technique for measuring the mass fractions of acetone and isopropanol using the internal standard method in the gas phase has been developed. n-Butanol was used as an internal standard. The detection limit was 1.45 for acetone, 1.43 for isopropanol, and 1.28 × 10–12 g/s for n-butanol. The relative standard deviation (repeability factor) did not exceed 4.3% at a confidence level Р = 0.95.
