Aliphatic amines atmospheric, determination

A determination of traces of low (Ci to C4) aliphatic amines in the atmosphere consists of passing air through an absorber containing phosphorous acid, derivatizing with m-toluyl chloride and end analysis by HPLC-UVD LOD 1-5 pmol of amine, corresponding to concentrations lower than 0.1 pg/m3 of air, in a 300 L sample232. 

Examples of the EKC determination of aliphatic amines in water compartments and atmospheric aerosol samples are compiled in Table 31.4. 

Most solvent products, especially organic solvents and some additives, emitted from paints and varnishes are VOCs. The largest components of VOCs are solvents, e.g., aliphatic and aromatic hydrocarbons, alcohols, amines, acids, aldehydes, esters, ketones, ter-penes. The defrnition of the term VOC varies, a standard definition is published by CEN (European Committee for Standardization) VOCs are any organic liquids and/or sohds that evaporate spontaneously at the prevailing temperature and pressure of the atmosphere. VOCC (volatile organic compound content) is defined as follows Mass of the volatile organic compounds in a coating material, as determined under specified conditions.
