Dumas Combustion Protein Analyzer

杜马斯燃烧蛋白质分析仪

High-throughput labs moving away from acid digestion often choose combustion. This analyser burns 50–500 mg samples at 900–1000 °C and reads nitrogen by thermal conductivity in 3–5 min, converting to protein with the factor you set. Plan for 99.999 percent helium carrier and oxygen at 2–3 bar when budgeting running costs.
