Benchtop CHN Analyzer for Routine Nitrogen-Protein Testing
用于常规氮-蛋白质检测的台式 CHN 分析仪
Food, feed and grain labs reporting protein can replace Kjeldahl digestion with fast Dumas combustion. This benchtop analyzer burns 100 mg–1 g at 950–1000 °C, measures nitrogen in 3–5 min with ≤0.5% RSD on EDTA, and offers C and H as options. Helium or argon carrier and a 40–100 position autosampler are available. Tell us daily sample numbers.
- Elements measured
- N (C, H optional)
- Sample mass
- 100 mg–1 g
- Nitrogen range
- 0.02–50 mg absolute N
- Nitrogen repeatability (RSD)
- ≤0.5% (EDTA standard)
- Combustion temperature
- 950–1000 °C

Food, feed and grain labs reporting protein can replace Kjeldahl digestion with fast Dumas combustion. This benchtop analyzer burns 100 mg–1 g at 950–1000 °C, measures nitrogen in 3–5 min with ≤0.5% RSD on EDTA, and offers C and H as options. Helium or argon carrier and a 40–100 position autosampler are available. Tell us daily sample numbers.
Highlights
- No acids or catalysts, unlike Kjeldahl
- Results in 3–5 min per sample
- Argon carrier option reduces helium dependence
- Large autosampler for grain trading volumes
Applications
- Food protein labelling
- Animal feed and pet food testing
- Grain and oilseed trading laboratories
- Fertilizer total nitrogen
