Why Choose our TIGER OPTICS Ultra-High Purity (UHP) Gas Analyzers?

Our ultra-high purity gas moisture analyzers and ppb moisture analyzers for specialty gases utilize CRDS technology, a highly sensitive, non-destructive method that delivers quantitative measurements of molecular absorption. This enables ultra-precise trace gas analysis in applications demanding the highest purity standards.

What is Cavity Ring-Down Spectroscopy (CRDS)?

CRDS is a laser-based optical measurement technology used to detect trace impurities in gases with exceptional sensitivity and stability.

Laser light reflects thousands of times between highly reflective mirrors. Trace gas molecules absorb a portion of the light, changing the ring-down time. This allows direct, highly selective measurements at ppb and ppt concentrations.

Benefits include:

• Exceptional sensitivity
• Direct optical measurement
• Fast response
• Minimal drift
• No consumable sensors
• Low maintenance
• Continuous operation
• High repeatability
