CHN Elemental Analyzer
Carbon, hydrogen and nitrogen in ~300 s: IR detection for C/H, thermal conductivity for N. 36-position autosampler with cycle loading.
- C/H/N in ~300 s per sample
- 36-position autosampler, insert-anywhere queue
- Repeatability: C ≤0.5 %, H ≤0.15 %, N ≤0.08 %
- ASTM D5373 & GB/T 30733 compliant

Overview
The RI-CHN2200 measures carbon (0.005–100 %), hydrogen (0.05–25 %) and nitrogen (0.01–50 %) in one run — infrared absorption for C and H, thermal conductivity for N. The pneumatic turntable loads 36 samples at once and accepts inserts at any position, so urgent samples are measured on arrival.
It is the most compact and lightest analyzer in its class, yet keeps a high-stability self-developed IR cell with low drift. Gas-path self-diagnosis pinpoints leaks automatically, and idle periods trigger automatic cool-down to save energy and extend heater life.
Key Features
Come-and-test workflow
Cycle loading plus arbitrary insertion means priority samples never wait behind a full batch.
Self-developed IR cell
Fully in-house, low-drift infrared cells for C and H — proven in thousands of field installations.
Automatic leak localization
Gas-path diagnostics identify the leak point automatically, turning day-long maintenance into minutes.
Remote supervision
Network interface streams results to LIMS and supervises the entire testing process for audit.
