Details

The DNPH (2,4-dinitrophenylhydrazine) active gas tube is a sampler capable of determining the concentration of aldehydes and ketones in the environment, typified by formaldehyde (HCHO), by using a pump to suction them from the atmosphere. The sampler immobilizes the airborne aldehydes and ketones by putting them in contact with silica gel impregnated with 2,4-dinitrophenylhydrazine (hereinafter "DNPH") in a polyethylene tube. Then after extracting the aldehydes and ketones with acetonitrile, they are measured by high-performance liquid chromatography (hereinafter "HPLC"). The product is best suited for use in measuring indoor environments.
