Automated Oxygen-Nitrogen-Hydrogen Analyzer with Autosampler

带自动进样器的自动氧氮氢分析仪

Production labs, testing services and additive manufacturing powder suppliers releasing many lots a day benefit from an autosampler on their ONH analyzer. This system loads 20–50 samples, cycles every 2–3 min and measures oxygen to 5%, nitrogen to 3% and hydrogen to 0.5%. Precision is ≤1.5% at 50 ppm O or N. Tell us your throughput.

Oxygen range: 0.1 ppm–5%
Nitrogen range: 0.1 ppm–3%
Hydrogen range: 0.1 ppm–0.5%
Sample mass: 0.1–1 g
Autosampler capacity: 20–50 samples
