GDX-202 stainless steel packed column
GDX-202 stainless steel packed column Details:

Stationary phase: copolymers such as styrene and divinylbenzene
Particle size: 80-100 mesh / 60-80 mesh
Material: Stainless steel
Specification: 2m*3mm
Application: Analysis of high boiling point compounds takes a short time and can also separate n-propanol-butanol

Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. used apex air phase chromatography to determine acetylene and vinyl chloride in hydrochloric acid solution produced by vinyl chloride production. Neutralization of hydrogen chloride in the sample was carried out using sodium hydroxide, thereby eliminating The effect of acetylene and vinyl chloride was analyzed by gas chromatography. The headspace equilibrium temperature was 35 °C, the equilibrium time was 45 min, and the column was a 2 m × 3 mm id stainless steel column filled with GDX-202 stationary phase. The column temperature was 140 °C. The head air injection volume is 1 mL. The external standard method quantifies the relative standard deviation of the acetylene content measurement to 0.85%; when the content is 30.0 μg/g to 150 μg/g, the recovery rate is 98.9% to 103%. The relative standard deviation of the determination of vinyl chloride content is 1.4%; when the content is 20.0 μg / g ~ 100 μg / g, the recovery is 98.8% ~ 102%.
