| Abstract |
Following an assessment of methods used to sample and analyse these 3 aldehydes, the materials, methods and instruments required for their quantitative determination in air are described (solvents, purification of 2,4-dinitrophenylhydrazine, reference substances and solutions, Amberlite XAD-2, preparation of chemisorption tube, high-performance liquid chromatograph (HPLC). The chemisorption and desorption trial procedures are detailed, and typical HPLC diagrams are reproduced. Brief descriptions of the sampling and analysis procedures to be followed for determining crotonaldehyde, benzaldehyde and p-methylbenzaldehyde concentrations in air. |
