CRDS Laser-Based Analyzer
CLASS I DIV II FOR HYDROCARBON FEEDSTOCKS AND SYNGAS
Introducing our TIGER OPTICS™ CO-rekt™ CW-CRDS trace-level analyzer for hydrogen brings the renowned benefits of our Cavity Ring-Down Spectroscopy to your HyCO and SMR plants. This analyzer is just in time to meet the growing demand for high-quality hydrogen feedstock,
This powerful, proven technology offers safe, fast and stable performance that allows you to efficiently manage your PSA beds to maximize yields and minimize contamination. It’s dynamic range spans over four orders of magnitude, from parts-per-billion to parts-per-million.
These analyzers require no calibration, eliminating the need for complex and costly calibration gas sampling systems, human intervention, and the frequent, risky movement of cylinders. With no interruptions for maintenance or unplanned shutdowns, the CO-rekt offers an extremely low cost of ownership and enables continuous online operation.
CW-CRDS (Continuous Wave Cavity Ringdown Spectroscopy) analyzers experience no temperature drift or spectral interference.
Our analyzers are impervious to vibration and proven to stand up to long-term use in industrial applications. Designed in collaboration with one of the world’s leading hydrogen manufacturers, the CO-rekt is guaranteed to increase uptime and decrease risk. Freedom from calibration allows users to operate with confidence and ease in the field.

APPLICATIONS
HYDROGEN PURITY
Sourcing high-purity hydrogen is critical to many diverse industrial applications where impurities impair yields. It is required for:
- Chemical production
- Metal refining
- Oil refining
- Food processing
- Semiconductor fabrication
BENEFITS
- Drift-free performance: It is so stable that it does not require calibration. No longer need to store and to manage calibration cylinders or pay for complex sampling systems. And remember, the less need for intervention, the less that can go wrong.
- No consumables and spare parts: The CO-rekt is all solid state. Lose those pesky choppers and save on repair costs, as well as inventory management and storage space.
- Packaged for plant use: With Class I, Div. 2 certification, the CO-rekt combines a purged NEMA enclosure with a space-saving wall-mount configuration designed for narrow instrument sheds.
- Insensitive to vibration: No more plant trips triggered by the mere slam of a door to the instrument shed. Protects up-time bonuses and avoids fines.
- Continuous online monitoring
- Wide dynamic range
- Excellent sensitivity with ppm-ppb level detection limits (LDL)
- Fast speed of response
