Carbon Hydrogen & Nitrogen Analyzer - QualiEA™ CHNA636

Carbon Hydrogen & Nitrogen Analyzer - QualiEA™ CHNA636 Features

High Automation

• Auto-loader with 36 positions (expandable to 72); samples can be added or replaced during testing.
• Fully automated sample feeding and analysis for continuous, unattended operation.

Automatic sample feeding and analysis enable fully unattended operation.

• Independent and precise thermostatic control for the analyzer and sensor unit stabilizes in just 90 minutes.

Short and Reliable Gas Path

• The integrated confluence board design ensures a compact gas path with low dead volume, minimal moisture residue, and precise automatic flow control — resulting in improved system reliability.

User-Friendly Design, Easy to Operate

• Air-tightness can be checked effortlessly through the software with a single click.
• The crucible can be replaced from the top of the analyzer, making it simple to change furnace reagents and disassemble the furnace when needed.

High Precision

• The sample introduction system features an air curtain design that prevents outside air from entering the furnace. A flow equalization unit ensures complete combustion, prevents sample splashing, and delivers accurate test results.
• High-performance infrared sensors precisely measure carbon and hydrogen while monitoring combustion in real time. This enables accurate assessment of combustion efficiency, faster analysis, and highly precise results.
• A high-sensitivity, low-drift diffusion-type thermal conductivity cell with independent thermostatic control ensures a stable and reliable thermal conductivity baseline.

Low Operating Cost

• The high-stability IR sensor reaches steady performance quickly. A built-in throttling device minimizes helium usage — only 0.7 L/min during testing and 0.05 L/min when idle — making the system more efficient and cost-effective than competing models.
