HALO Max QCL CO2

Expanding Optical Contaminant Detection Capabilities for Semiconductor Manufacturing

Tiger Optics takes Cavity Ring-Down Spectroscopy (CRDS) to the next level by bringing you the latest optical technology. Utilizing mid-infrared Quantum Cascade Lasers (QCLs), the new HALO Max QCL allows dramatic decreases in detection limits for certain molecules, such as CO2.

Introducing the HALO Max QCL CO2 for ppt-level carbon dioxide detection, it is based on Tiger Optics’ latest Max platform, offers exceptional speed and further improved usability in an all-inclusive and robust package. The analyzer is fast to install, offers continuous, real-time detection, and is easy to use and effortless to maintain, with built-in zero verification and zero drift.

The HALO Max QCL CO2 perfectly complement Tiger’s HALO KA Max series (for H2O, NH3 and CH4), the HALO OK (for O2) and our other QCL-based analyzer, the HALO Max QCL CO to utilize the advantages of CRDS for detection of a large variety of critical trace impurities.

Detectie

Detection and Matrix Range* LDL (3σ) Precision (1σ) @ zero
CO2 in N2 0 – 0.4 ppm 100 ppt 35 ppt
CO2 in He 0 – 0.4 ppm 90 ppt 30 ppt
CO2 in Ar 0 – 0.4 ppm 90 ppt 30 ppt
CO2 in O2 0 – 0.4 ppm 90 ppt 30 ppt
CO2 in Clean Dry Air (CDA) 0 – 0.4 ppm 100 ppt 35 ppt
*Higher range is available upon request.
Due to the high abundance of CO2 in air,
purging of the analyzer housing is required
to achieve specified LDL (see previous page
for purge gas requirements)
