Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used pre column derivatization gas chromatography to separate and determine the coexisting pentaerythritol (MPE) and dipentaerythritol (DPE) in the reaction mixture. The derivatization reaction was carried out in a closed test tube heated at 120 鈩�, and a stainless steel tube (2 m × 3 mm) containing 10% OV-101 and 180-150 μ m 101AW-DMCS was used as the chromatographic column for separation and determination. The RSD values of the obtained results were less than 0.21% when measuring MPE and less than 0.18% when measuring DPE. The deviation between the measured value and the standard value is less than 0.9%.
Name: Stainless Steel Filled Column
