29 Multiple Uses of Nitrosamine Testing in the Brewing Industry
NDMA is a known animal carcinogen and is produced as a biproduct during the kiln drying phase of the malting process. Whilst techniques are utilised to minimise the formation of nitrosamines low levels of carcinogens may remain. To regulate the exposure of nitrosamines from the consumed liquid it is vital to monitor levels of NDMA within the malt and the final product. This can be achieved using the Ellutia 800 Series Thermal Energy Analyser (TEA) interfaced with a gas chromatograph. Its simple operation, very high sensitivity and very high selectivity for nitroso compounds makes the TEA a superior choice of detector for this application.
Brewing plants should be caustically cleaned on a regular basis. The effectiveness of cleaning can be assessed by analysing the levels of apparent total N-nitroso compounds (ATNC). This acts as measure of microbiological contamination; as a source of the N-nitroso compounds is from bacteria species with nitrate reductase activity.
ATNC does not require speciation, therefore a GC is not required to perform separation prior to analysis. Ellutia has developed a glassware interface for the 800 series TEA which streamlines the analysis process. This method is included in industry standards set by food safety certification schemes, such as SALSA

The Use of Gas Chromatography to Test for Traces of Explosives
800 Series TEA
Nitro, Nitroso & Nitrogen Detector
Chromatography can be an extremely valuable tool in the detection of explosives. Following an explosion, it is crucial to a police investigation to identify if an explosive was used, and if so what type. Finding traces of explosives on a suspects clothing or belongings can link that suspect to a case. Once trace samples are collected, the amount of explosives in the sample can be on the low nanogram range.
TEA detectors, coupled with GC are widely used for the forensic analysis of trace explosives. Its simple operation, very high sensitivity and very high selectivity for nitroso compounds, makes the TEA a superior choice of detector for this application.
The Ellutia 800 series TEA is already being used in the world class Dubai Police science and criminology laboratory, and a detailed case study can be found on Ellutia’s website.
