Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has studied the gas chromatography separation conditions of pentaerythritol and the quantitative method of pentaerythritol. The purity of the standard sample of pentaerythritol was determined, and the peak height quantitative method was used to determine the content of pentaerythritol in commercial pentaerythritol. The relative standard deviation was less than 1%.
GB/T 7815-2008 Pentaerythritol for Industrial Use
GB/T 7815-2008 Pentaerythritol for Industrial Use
