The DuMaster D-480 enables unattended and flexible determination of nitrogen or protein according to the Dumas combustion method. The short analysis time of approximately 4 minutes per sample, coupled with the built-in autosampler accommodating up to 120 samples, makes this instrument perfectly suitable for high throughput without supervision.

Unattended and fast

·      Rapid analysis times of approximately 4 to 6 minutes per sample

·      High sample throughput due to fast and automatic autosampler

·      Unattended over-night operation of up to 120 samples

·      Continuous operation thanks to stable conditions over months

Cost effective

·      Automated oxygen control saves up to 95% of oxygen consumption

·      Low-price carbon dioxide as carrier gas as opposed to helium

·      Low costs per sample thanks to high degree of automation and low consumable costs

Safe and convenient

·      No contact with harmful chemicals or burn risks

·      Large sample volume (up to 1 g or 1 mL) analysis thanks to efficient multi-step gas drying

·      Random access of samples at any time (no batch processing required)

·      Remote assistance and troubleshooting over the internet
