Determination of acetaldehyde and propionyl aldehyde with PEG-20M/6201 stainless steel packed column
PEG-20M/6201 stainless steel packed column for determination of acetaldehyde and propionaldehyde. Details:

Acetaldehyde (CH3CHO) is a colorless and volatile liquid. It can emit irritating vapors under normal temperature and pressure. It is a slightly toxic substance. It has a stronger inhibitory effect on the central nervous system than formaldehyde. Its toxic and side effects on humans are mainly irritation to the skin, mucous membranes and Inhalation of steam from the respiratory tract causes harm to human nerves, liver and other organs. Propyl aldehyde (CH2CHCHO) is a colorless, transparent and volatile liquid with a special pungent odor and is a highly toxic substance.
Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. uses packed columns. The detection limits of this method for acetaldehyde and propionyl aldehyde are 0.0012 mg/L and 0.0006 mg/L, respectively, and the relative standard deviations are 3.5%～6.9%. , 2.9%～5.8%, and the recovery rates of standard addition are 91.6%～108%, 92.0%～105%. Compared with the analytical method recommended by GB, this method has the characteristics of simple operation, high sensitivity, good repeatability, and basically does not consume organic solvents. It can meet the determination requirements of acetaldehyde and propionaldehyde in surface water and wastewater.
