Hanon Dumas Nitrogen/Protein Analyzer determines the nitrogen/protein content of samples through combustion, purification, reduction, and thermal conductivity detection. It efficiently analyzes a single sample in 4 minutes without pretreatment and reacts in a nontoxic and harmless way to ensure safety and environmental friendliness.

• Considerable: a 1-disc 120-position autosampler (D200 only) is adopted to directly analyze a large number of samples
• lQuick: the fast cooling function helps the device reach the shutdown temperature in 30 minutes
• lPremium: core pneumatic components of SMC® and mass flow controllers of Bronkhorst® retain the reliability for a long time
• lCost-effective: new consumables and efficient metal condenser dewatering technologies extend the service life
