Detection of Phenolic Compounds in Polycarbonate by Capillary Column
Capillary Column Detection of Phenolic Compounds in Polycarbonate Materials Details:

Name: capillary column
Stationary Phase: 5% Phenyl-95% Methylpolysiloxane
Specifications: 30m*0.25mm*0.25um
Model: HH-5
Application: T/HZAS 19-2021 Polycarbonate Materials Determination of Phenolic Compounds Gas Chromatography-Mass Spectrometry


Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a gas-phase rapid detection method for phenolic compounds such as 2-tert-butylphenol, 4-tert-butylphenol and 2,4-di-tert-butylphenol in polycarbonate plastic packaging materials. Chromatography mass spectrometry. The samples were extracted by n-hexane ultrasonic extraction, centrifuged, concentrated, and then determined by GC/MS, and quantified by external standard method. The results showed that 2-tert-butylphenol, 4-tert-butylphenol and 2,4-di-tert-butylphenol had good linear relationships in the range of 0.1100 mg/L, respectively. The recovery rates of the three phenolic compounds were 82.23% 92.31% at 4 levels, and the relative standard deviations were 2.13% 4.76% (n=6). The method has excellent sensitivity and stability, and meets the requirements for the analysis and detection of phenolic compounds such as 2-tert-butylphenol, 4-tert-butylphenol and 2,4-di-tert-butylphenol in polycarbonate plastic packaging materials. Accurate quantification.
