Determination of a small amount of methanol in liquid ammonia by capillary column
Determination of a small amount of methanol in liquid ammonia by capillary column Details:

Name: capillary column
Stationary phase: styrene-divinylbenzene
Specification: 30m * 0.53mm * 40um
Model: HH-PLOT-Q

Tengzhou Haohan Chromatographic Instrument Technology Service Co., Ltd. applied gas chromatography to determine the methanol content in liquid ammonia. The liquid ammonia diluted with water was driven into a chromatographic column with a nitrogen carrier gas. Polystyrene-divinylbenzene (HH -PLOT-Q column) is a stationary phase, which is detected by a hydrogen flame ionization detector. The external standard method is used to determine and quantify the methanol in liquid ammonia by using the retention time and peak area of the standard sample. Methanol has a short analysis time, high sensitivity, and good repeatability. The comparison of the measurement results with the standard values proves that the method for determining the methanol content in liquid ammonia by gas chromatography is feasible.
