A simple, rapid, accurate and precise analytical method for determination of secondary and tertiary amines in hydrochloride salt form of drug substances in non-aqueous medium, which does not require any derivatization, was developed by headspace gas chromatography. Dimethylamine hydrochloride and triethylamine hydrochloride were analyzed in metformin hydrochloride. The sample was dissolved in a vial containing dimethyl sulphoxide and imidazole. The vials were incubated at 100°, for 20 min. The syringe temperature was maintained at 110°. DB624 column with 30 m×0.32 mm i.d., 1.8 µm film thickness was used. The injector and detector temperature were 200° and 250°, respectively. The analytical program used was carrier gas (nitrogen) flow rate: 1 ml/min; injected gas volume: 1.0 ml; split ratio: 1:10; oven temperature program: 40° for 10 min, followed by an increase up to 240° at 40°/min. The analytical method was validated with respect to precision, recovery, limit of detection and quantification and linearity.

“…One example of a con-trolled and intensified way to degrade organic material is composting. In the headspace of composting facilities high concentrations of amines, especially TMA, have been found (Maris et al, 1999;Mao et al, 2006;Tsai et al, 2008). Emission of NH 3 from senescent and decaying plant material has been described, and corresponding values have been evaluated Mattsson et al, 2009;Massad et al, 2010a;Flechard et al, 2013).…”

Ideas and perspectives: on the emission of amines from terrestrial vegetation in the context of new atmospheric particle formation

Abstract. In this article we summarise recent science which shows how airborne amines, specifically methylamines (MAs), play a key role in new atmospheric particle formation (NPF) by stabilising small molecule clusters. Agricultural emissions are assumed to constitute the most important MA source, but given the short atmospheric residence time of MAs, they can hardly have a direct impact on NPF events observed in remote regions. This leads us to the presentation of existing knowledge focussing on natural vegetationrelated MA sources. High MA contents as well as emissions by plants was already described in the 19th century. Strong MA emissions predominantly occur during flowering as part of a pollination strategy. The behaviour is species-specific, but examples of such species are common and widespread. In addition, vegetative plant tissue exhibiting high amounts of MAs might potentially lead to significant emissions. The decomposition of organic material constitutes another, potentially ubiquitous, source of airborne MAs. These mechanisms would provide sources, which could be crucial for the amine's role in NPF, especially in remote regions. Knowledge about vegetation-related amine emissions is, however, very limited, and thus it is also an open question how global change and the intensified cycling of reactive nitrogen over the last 200 years have altered amine emissions from vegetation with a corresponding effect on NPF.
