John Morris Scientific has introduced Gerhardt's Dumatherm single-filament gas analyser, which quickly determines nitrogen according to the Dumas method.
The Dumatherm features short internal connections for results within two to three minutes.
It needs little maintenance and its corrosion-resistant media wetted parts ensure a long service life.
In the Dumas method, a solid or liquid sample is combusted in an oxygen-rich environment at high temperatures and then passed through a series of thermal conductivity detectors for fast, precise and cost-efficient measurements.
The Dumatherm's computer-optimised parameters automate operation, which minimises supervision by laboratory staff.
The user-friendly software provides powerful diagnosis and documentation functions as well as easy data interpretation for non-technical personnel.
The Dumatherm allows determination of nitrogen in milk, dairy products, soil conditioners, culture media, oilseeds and feeds.
It can also be used to determine crude protein in cereal grain, in meat products and in animal feed.
