Gas Analyzers

Picarro’s trace gas analyzer family is designed to meet the demanding requirements of industrial process applications.  Based on a revolutionary technology known as Cavity Ring-Down Spectroscopy (CRDS), these analyzers deliver world-class detection sensitivity and selectivity with exceptional measurement speed.  Picarro’s family of innovative ultra-trace gas analyzers are based on our proprietary and patented CRDS technology, and have been designed for reliability at every step. The result is a process-worthy trace gas analyzer—advanced technology that works.

CRDS uses narrow-frequency, telecommunications-grade, tunable laser diodes with an ultra-high finesse optical cell which delivers unmatched spectral resolution -- (0.0001 cm-1) ~-1000 times better than an FTIR.  The high finesse optical cell results in an effective path length of ~20 km from a physical cell length of ~20 cm.  These two important attributes of the CRDS technique result in extraordinary spectral separation between a target chemical species and any background species, plus extreme sensitivity to ultra-low concentrations of the target species.

The family of trace gas analyzers is simplifying previously difficult measurements, as well as enabling completely new measurements in application areas as diverse as semiconductor manufacturing, diesel emissions analysis, environmental monitoring and petrochemical process control.
