TN/Protein analyzer Primacs SNC100

Routine monitoring Total Nitrogen /Protein content during the brewing process is important to ensure the quality & stability of the beer products. Protein present in malt and wort are important nutrients for yeast to ferment wort into beer. By measuring Nitrogen, we can indicate the protein content in malt and wort. Classical Nitrogen measurement is done via the Kjeldahl method. The Kjeldahl method is not easy to automate, additionally the analysis time takes an hour or more and toxic or harmful reagents are used. Therefore, Skalar has developed an analyzer which fits better in the Brewing industry. The PrimacsSN-100 provides fast, efficient and accurate analysis results for Total Nitrogen (TN) / Protein in malt and wort by using high temperature combustion according to Dumas methodology. The analyzer contains an integrated autosampler with 100 positions. The sample rack is removable and re-usable ceramic crucibles are used for sample weights up to 3 g of solids and up to 1 g of liquid material. Samples are automatically introduced in the high temperature combustion furnace through a unique vertical sample introduction system. Sample ashes remain in the crucible after the analysis and are taken out of the instrument with removal of the crucible. This avoids sample ash build-up in the combustion zone and therefore reduces maintenance. In the combustion furnace, Nitrogen is converted into NxOy in presence of Oxygen. In the reduction furnace all Nitrogen is reduced to N2. The N2 gas is measured by Thermal Conductivity Detection (TCD).
