Determination of Residual Monomers of Propylene Oxide (PO) in Polyether Polyols
Determination of Residual Monomers of Propylene Oxide (PO) in Polyether Polyols Details:

Name: capillary column
Stationary Phase: 5% Phenyl-95% Methylpolysiloxane
Specifications: 30m*0.32mm*0.5um
Model: HH-5
Application: Determination of trace monomer propylene oxide content in polyether polyols

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. investigated the feasibility of the static headspace sampling external standard method and the standard addition method to determine the residual amount of propylene oxide in polyether, and determined that the polyether to be tested was used as the matrix, and the quantitative addition of cyclic Quantitative analytical method by standard addition of oxypropane. Chromatography using GC-, equipped with HH-5 capillary column (30 m × 0.32 mm × 0.5um) and hydrogen flame ionization detector (FID). The relative standard deviation of the micromonomer determination results was 10%, and the detection limit was as low as 3×10-6. The method has the advantages of strong adaptability, accuracy and simplicity.
