CRDS Laser-Based Analyzer
TRACE GAS ANALYZER FOR DEUTERIUM QUALITY ASSURANCE
Deuterium (D2 or 2H2), also known as “heavy hydrogen”, is used in a variety of applications, including industrial and university research comparisons between the hydrogen and deuterium in deposited film analysis, rapid thermal anneals for certain semiconductor devices, and optical fiber manufacturing to eliminate the water peak in the telecom E-band.
Whether for process control or quality assurance, gas suppliers need accurate, low-level contaminant monitoring to ensure deuterium purity, especially for trace D2O (heavy water) and HDO (semi heavy water). The HALO 3 D2O/HDO analyzer offers unparalleled accuracy and reliability for your deuterium purity analysis. Compact and easy to use, this analyzer features our proven Cavity Ring-Down Spectroscopy technology to effortlessly detect single-digit ppb levels of D2O and HDO in your sample.
Users enjoy freedom from periodic sensor maintenance, and with no calibration gases required, operating costs are nearly eliminated. With drift-free stability and rapid response time, the HALO 3 D2O/HDO analyzer is ideal for continuous, online gas monitoring that is critical to process control in gas and chemical industries or anywhere purity is a necessity.
THE HALO 3 D2O/HDO ANALYZER ENSURES PURITY AND PROCESS PROTECTION WITH:
- Parts-per-billion (ppb) D2O and HDO detection capability
- Wide measurement range
- Freedom from calibration (absolute CRDS measurement technology)
- Low cost of ownership and zero maintenance
- Easy to use touchscreen and remote software interface
