Friday, 08 October, 2021 | Supplied by: Bio-Strategy Pty Ltd


For the determination of nitrogen and protein in food, there are different established methods. As well as the classic Kjeldahl method, nowadays the faster Dumas method has become more and more accepted. This can be seen from the fact that the Dumas method is indicated as an additional reference method in various international standards. C. Gerhardt provides users with two options for automated protein analysis: Kjeldahl analysis with VAPODEST and Dumas analysis with DUMATHERM.

The VAPODEST 500 C has everything onboard for fully automated Kjeldahl analysis, which is still the universal reference method for all sample matrices. Designed for continuous operation with large sample numbers, the system is equipped with an autosampler to do 20 analyses in series. Titration during distillation reduces the analysis time, while the system’s intelligent monitoring and components are said to meet the highest safety standards.

The DUMATHERM N Pro meanwhile offers rapid Dumas (combustion) analysis within 3 min, with a system that handles up to a 156-position autosampler. Exhaust equipment is not required for the virtually chemical-free process, which also has low usage of consumables and low gas consumption, consuming 50% less helium than other systems according to the company. Components are easily accessible and maintenance can be carried out within a few minutes.
