In Vitro Technologies now has available Buchi’s expanded product portfolio that includes Dumas technology. The company says it is the only provider of all three key technologies - Kjeldahl, Dumas and NIR.

The Buchi DuMaster D-480 analyser utilises the Dumas method, which is mainly used in the food, beverage, feed and agriculture industries for the determination of protein in food/feedstuffs or total nitrogen in fertilisers or soils.

Dumas technology can be applied to almost all Kjeldahl applications including: production and quality control in the food/beverage and feed industry; universities and research laboratories; private or public testing laboratories.

The DuMaster D-480 analyser is supplied ready to use including operating software and 60-position auto sampler. Unattended operation with random access allows samples to be loaded at any time.

The device features a reduced operational cost as the system uses CO₂ as carrier gas instead of helium, 95% less oxygen consumption and 3x higher reduction capacity of tungsten (as opposed to competitive Dumas instruments which use copper as reducing agent).

The unattended and fast operation lowers operating cost per sample.

Other key features include: short analysis time; an option to increase sample throughput up to 120 samples; highest sample throughput without supervision.

The device is safe and convenient, with samples able to be loaded at any time (random access vs batch processing); low-voltage furnace; suitable for flexible evaluation of samples.

There is no contact with harmful chemicals and the Dumas method is compliant with AOAC, ISO, DIN and other authorities.
