Abstract
A procedure was proposed for the 2D gas-chromatographic determination of C1-C4 hydrocarbons in high-purity silane. The impurities were separated in a capillary column with a newly proposed adsorbent, poly(trimethylsilylpropyne). The detection limits for the impurities are (2−6) × 10−7 vol %, which is 2.5–15 times lower than those found in the literature.
