Thermo Scientific HH-WAX Capillary Column
Thermo Scientific HH-WAX Capillary Column Details:

Name: Capillary column
Fixative: polyethylene glycol
Specifications: 60m*0.25mm*0.25um
Model: Thermo Fisher HH-WAX
Application: GB 5009.266-2016 National Food Safety Standard Determination of methanol in food

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd., took a sample of 0.100 0g and dissolved it with 5.0 mL of water, and introduced it into the headspace sampler. It was heated at 80°C for 30 minutes to reach equilibrium. After the methanol in the solution was extracted by headspace, HH-WAX capillary chromatography column was used as the stationary phase for gas chromatography separation. In the mass spectrometry analysis, the selected ion monitoring mode is adopted, and the external standard method is used for quantification. The mass concentration of methanol is linearly related to its peak area within 0.50~100mg·L~(-1), and the detection limit (3S/N) is 0.002 5%. The recovery test was carried out according to the standard addition method, and the measured recovery rate was between 90.0% and , and the relative standard deviation (n=6) of the measured values was less than 2.2%.
