GB/T 17815-2018 Determination of Propionic Acid and Propionate in Feeds PEG-20M Capillary Column Details:
Name: capillary column
Stationary solution: polyethylene glycol
Specification: 30m * 0.25mm * 0.5um
Model: PEG-20M
Application: GB/T 17815-2018 Determination of propionic acid and propionate in feeds
A method for the determination of propionic acid and propionate in feed by gas chromatography was established by Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. After the sample was treated with suan acid hua, propionate was converted into propionic acid, extracted with ethylamine, and the capillary column PEG-20M, 30m × 0.25mm × zero point five μ m) The results showed that the linear range of the method was 5.0-500mg/L (R=0.9993), the detected XIAN was 0.77mg/kg, the recovery of propionic acid was 87.2% - 93.4%, and the relative standard deviation was 1.7% - 3.2%
