Carbon and Nitrogen Analyser [Vario Max Cube]

Samples are combusted to 800-900°C, oxygen and water vapour are removed, and the remaining gas analysed.
Uses the Dumas combustio method, which is superior in all ways to wet chemical methods.
90 position autosampler for samples of up to 5g, with times as low as 4 minutes per sample when detecting just nitrogen.
Precise enough to detect N at a rate of 5 ppm in beer, or 10 ppm of C in a soil sample.
