A simple field test for the determination of acetone vapour in air

Abstract

A field method is described for the determination of acetone vapour in air in concentrations up to 2000 p.p.m. v/v. The vapour is collected in a solution containing sodium nitroprusside and ammonium acetate. On the addition of ammonia solution, a coloured complex is formed, which is compared visually with standards after 10 minutes. Two series of standards are used, the choice of which depends upon the temperature at which colour development is carried out. Both apparatus and method are simple and a complete determination can be carried out in about 15 minutes.
