CRDS Laser-Based Analyzer
ADVANCING ACCURATE, CONSISTENT & DRIFT-FREE CO2 MEASUREMENTS
The removal of contaminants prior to cooling and distillation is essential to the cryogenic air separation process. If not detected quickly, impurities such as CO2 (carbon dioxide) can freeze in the downstream cryogenic equipment causing damage and product spoilage. Our TIGER OPTICS™ HALO™ 3 CO2 analyzer affords fast, accurate response and clean-up, with no possibility of drift. Based on powerful Cavity Ring-Down Spectroscopy (CRDS), with a proprietary laser-locked cell, the HALO 3 is free of drift, guaranteeing consistent and reliable trace CO2 detection in nitrogen and other inert gases. Highly specific to the target molecule, CRDS also prevents cross interferences from distorting your measurement. Plus, there is no need to perform costly and time-consuming zero and span calibrations, saving both time and money with continuous, on-line service.

Compact and portable, the HALO 3 CO2 gives you unsurpassed speed of response and ease of use. In sum, the Halo 3 CO2 analyzer serves a range of applications where trace gas measurement is extremely critical, such as syngas production, fixed bulk gas continuous monitoring, gas cylinder quality control, auto-load truck fill and a multitude of other challenging applications. The HALO 3 CO2 builds on our longstanding leadership for trace monitoring of critical compounds in pressurized gases.
THE HALO 3 CO2 OFFERS BEST-IN-CLASS PERFORMANCE INCLUDING:
- Lower detection limit down to 8 ppb in nitrogen
- Wide dynamic range
- Freedom from drift
- No spectral interference
- Compact standalone footprint or rack mountable
- Low Cost of Ownership
- Simple operation
