Develop a simple, fast, high-sensitivity, high-recovery, reproducible, non-polluting method for measuring the methanol content of various cosmetics. Direct headspace gas chromatography was used to determine the methanol content in cosmetics.
Tengzhou Haohan Chromatographic Instrument Technology Service Co., Ltd. uses skin care and health care products as the main research object and uses gas chromatography to study the methanol content in skin care and health care products with different viscosities. The results showed that methanol had a good linear relationship in the concentration range of 20 ~ 2000μg / ml, and the correlation coefficient was 0.9994. The detection limit (3S / N) of the method is 6.0 μg / g. The recovery rate of methanol was tested at three different addition levels. The average recovery rate of the method was 93.29%. The method is simple, fast, and sensitive. It is suitable for skin care Detection of methanol content in products.
