“…Relative amounts of dimethylamine (DMA) and ammonia (NH 3 ) predicted in the particle phase, expressed as fractions of total base predicted in the particle phase, as a function of gas-phase DMA and NH 3 levels (gas-phase acetic acid=100 ppt). have been reported, on the order of tens to hundreds of ppb (Rabaud et al, 2003;Rampfl et al, 2008). The second system type (ST 2) was designed to investigate the contribution of organic salt formation to the reduction in volatility of organic acids and bases from nanometersized particles.…”

“…Table 3 lists the low and high levels of five aliphatic amines measured by Grönberg et al (1992), and their K H and pK a values. Those values, along with gas-phase amine levels reported by Rampfl et al (2008), were used here to represent a range of possible values for ambient amines. For these general considerations, the fraction of amines in the particle phase (f amines =n amines,p /n totalbase,p , where n is mols) is shown in Fig.…”

Abstract. Field and lab measurements suggest that lowmolecular weight (MW) organic acids and bases exist in accumulation and nucleation mode particles, despite their relatively high pure-liquid vapor pressures. The mechanism(s) by which such compounds contribute to the mass growth of existing aerosol particles and newly formed particles has not been thoroughly explored. One mechanism by which low-MW compounds may contribute to new particle growth is through the formation of organic salts. In this paper we use thermodynamic modeling to explore the potential for organic salt formation by atmospherically relevant organic acids and bases for two system types: one in which the relative contribution of ammonia vs. amines in forming organic salts was evaluated, the other in which the decrease in volatility of organic acids and bases due to organic salt formation was assessed. The modeling approach employed relied heavily on group contribution and other estimation methods for necessary physical and chemical parameters. The results of this work suggest that amines may be an important contributor to organic salt formation, and that experimental data are greatly needed to improve our understanding of organic salt formation in atmospherically relevant systems and to accurately predict the potential contribution of such salts to new particle growth.

Polyfunctional amines are a group of substances commonly used as additives or monomers in food-contact materials. These substances can migrate into foodstuffs and, consequently, may be potentially dangerous for human health. Due to their different chemical structures and physicochemical properties there does not exist a standard method to analyze polyfunctional amines. This review aims to provide an update on the chromatographic methods used for the determination of polyfunctional amines that are commonly used in the manufacture of food packaging materials. Detailed information regarding chromatographic conditions (mobile phases, chromatographic columns, detection systems, and so on) is provided. Moreover, chemical structures and physicochemical properties of the substances studied are also presented.
