Measure using a gas chromatograph with a hydrogen flame ionization detector and convert it to the total carbon content. The results showed that possible carbon containing substances such as methyldichlorosilane, methyltrichlorosilane, and dimethyldichlorosilane in high-purity trichlorosilane all had good conversion rates in the conversion furnace, with conversion rates exceeding 85%. The determination results of carbon content in the sample have good repeatability and high precision, with relative standard deviations less than 10%. The method is simple, fast, and has high accuracy, which can well meet the quality control requirements for carbon containing substances in high-purity trichlorosilane samples.
