Safe and accurate analysis of explosive compounds ...
Exeter Analytical has released a new application note that describes a safe and accurate analytical method for accurately determining the percentage Nitrogen (N) content of explosive materials such as pentanitrocellulose, dekanitrocellulose, and pyroxylin. Historically, the nitrogen content of nitrocellulose compounds, as well as other munitions, has been analysed with a nitrometer using the standard method MIL-STD-286B (T-209.9). However not only is this method labour intensive, but it also potentially exposes the operator to harmful mercury vapours. For nitrocellulose compounds, and other explosive materials, Exeter Analytical has developed a new safe and accurate percentage nitrogen determination method based upon their Model CE440 Elemental Analyser. Application note TM212 describes the new methodology and demonstrates how theoretical values of nitrogen compare closely with data obtained from standard method MIL-STD-286B (T-209.9). The Exeter Analytical CE440 Elemental Analyser uses thermal conductivity detectors to simultaneously analyse for nitrogen, carbon and hydrogen content. Interferences are removed through column packings and the combusted sample is converted into non-toxic carbon dioxide, water vapour and nitrogen. Exeter Analytical (www.exeteranalytical.co.uk) is a company dedicated to elemental analysis. Through many years continuous investment in product development and listening to its customers the Exeter Model CE-440 CHN/O/S Elemental Analyser, with its unique horizontal furnace design, is widely viewed to be the most accurate and precise analyser available on the market today, with the broadest range of sample applications.
