The analyzer is based on Picarro’s unique Cavity Ring Down Spectroscopy (CRDS), a time-based measurement utilizing a near-infrared laser to measure a spectral signature of the molecule. Gas is circulated in an optical measurement cavity with an effective path length of up to 20 kilometers. A patented, high-precision wavelength monitor makes certain that only the spectral feature of interest is being monitored, greatly reducing the analyzer’s sensitivity to interfering gas species, and enabling ultra-trace gas concentration measurements even if there are other gases present. As a result, the analyzer maintains high linearity, precision, and accuracy over changing environmental conditions with minimal calibration required. Precise temperature and pressure control systems designed into the Picarro G2205 ensure accurate measurements over long periods of time with minimal use of calibration gases. The analyzer is exceptionally rugged, essentially drift and maintenance free, and requires no consumables, thereby offering significant ease of use and cost of ownership benefits.Easily transportable from site to site, the analyzer can be set up and running within minutes, and require no sample preparation except drying. The gas concentration is displayed in real-time with no post-processing required, and is continuously archived to the analyzer’s internal hard drive. Designed to operate both in laboratories and in harsh environments, it can operate for many months without user interaction. The analyzer can be configured to automatically send out measurement data at regular intervals via the Ethernet or optional modem and can output real-time data in digital format (via RS-232 interface) and via optional analog outputs. Users can connect remotely with the analyzer’s internal Windows-based PC and control it through a standard Remote Desktop connection or with similar remote login software. The analyzer can also use its modem or Ethernet connection to automatically synchronize with an atomic clock time service. The software includes a valve sequencer, capable of controlling controlling up to six external solenoid valves and a rotary valve.Performance SpecificationsTarget Gas (in air-like matrix)Lower Detectable Limit* (5 min., 3s)*Guaranteed over operating conditions below, after 1-hour equilibration.
