Dumas Nitrogen\/Protein Analyzer<\/h3><\/div>

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.<\/p>
