Analysis of solid and liquid samples using the combustion method according to Dumas can be performed quickly and easily with Gerhardt’s Dumatherm DT N equipment. The analysis takes place within 3 minutes for all standard sample matrices weighing up to 1 g. It offers the possibility of analysing a fluctuating amount of samples during the production process. For most matrices, the Dumas method is a fast and reliable alternative to the classical digestion method like Kjeldahl. Nowadays, both methods are considered equivalent reference methods. The determination of nitrogen and proteins can be performed on a variety of food products, such as feed material, oilseeds, meat-based products, culture media, and so on. The equipment is available in manual version with 2-place sampler, or in automatic version with automatic sampler for 40/64 samples. Astori Tecnica has been Gerhardt’s distributor and authorized service center in Italy for many years, and offers technical assistance for the entire range of equipment.
