Packed column for determination of acetaldehyde in ambient air and industrial waste gas
Packed column for determination of acetaldehyde in ambient air and industrial waste gas Details:

Name: Filled glass column
Specification: 2m*3mm (inner diameter)
Model: 20%PEG-20M/GCS880 AW DMCS (80-100 mesh)
Application: HJ/T 35-1999 Determination of Acetaldehyde in Exhaust from Stationary Pollution Source Gas Chromatography

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses gas chromatography to determine acetaldehyde in ambient air and industrial waste gas. Enriched and absorbed with 1% NaHSO 3 solution, PEG-20M was used as the stationary liquid, GCS-880-AW-DMCS was used as the carrier, and the hydrogen flame ionization detector was used for chromatographic determination. The sampling method, sample storage and optimal chromatographic conditions are studied. The sampling efficiency of the method is not less than 99.0%; the precision and accuracy are both high; the minimum detection concentration of the method is 0.04mg/m~3.
