The design of the Optograf process analyzer incorporates customer requirements for serviceability and hazard-area certification, provides a compact footprint, and minimizes utilities consumption. The high optical efficiency of the Optograf process Raman analyzer makes it ideal for measurement of gas-phase samples.
Raman Rxn5 Analyzer
Description
Turn-key process Raman analyzer for quantitative chemical composition measurements
The Raman Rxn5 Analyzer is an industry-leading, turn-key, laser-based analyzer that provides quantitative chemical composition measurements using Raman spectroscopy. The design of the Optograf process analyzer incorporates customer requirements for serviceability and hazard-area certification, provides a compact footprint, and minimizes utilities consumption. The high optical efficiency of the Optograf process Raman analyzer makes it ideal for measurement of gas-phase samples.
Benefits
- Non-destructive analysis of gases, including homonuclear diatomics (H2, N2, O2)
- Compact, smaller than most wall-mount GCs
- Can replace up to four traditional analyzers with a single base unit and four probes
- Rugged with minimal utility requirements, no sample transport, and no consumables (columns, valves, gases, pumps)
- Minimal analyzer technician time with maximum technician safety (no toxic gases are transported to the analyzer)
- Measures four streams simultaneously for faster multi-channel results
- -20°C to + 50°C operating environment
Field of application
