Gas Analyzer

Picarro analyzers are among the world's most sensitive and easy to use real-time gas analyzers for trace detection, many with typical lower detection limits of parts per trillion. In addition to their unprecedented sensitivity, the analyzers operate with no requirement for frequent calibration and with immunity to cross-talk from any other gas component in the sample, including varying moisture levels. These simple to use analyzers can be operated remotely, producing virtually drift-free data over months of operation without calibration. The high dynamic range of these rugged analyzers means they can deliver linear response for concentrations ranging from ppt to % levels, with an absolute accuracy of much less than 1%. Many analyzers offer the ability to simultaneously measure multiple gases in the same low-volume sample cell. This compact cell design minimizes the sample exchange time enabling very fast response times.

All Picarro analyzers are based on Picarro's unique Wavelength-Scanned Cavity Ring Down Spectroscopy (WS-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 absorption feature of interest is being monitored, greatly reducing the analyzer's sensitivity to interfering gas species, and enabling ultra-trace gas concentration and isotope 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 analyzers ensure accurate measurements over long periods of time with minimal use of calibration gases. The analyzers are exceptionally rugged, essentially drift and maintenance free, and require no consumables, thereby offering significant ease of use and cost of ownership benefits.

Easily transportable from site to site, Picarro's analyzers can be set up and running within minutes, and require no absolutely sample preparation or drying. The gas concentration is displayed in real-time with no post-processing required. Designed to operate both in laboratories and in harsh environments, the analyzers can operate for many months without user interaction. The analyzers 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 (via RS-232 interface) and optional analog data formats as well. It is possible to remotely connect 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.
Qualities common to all Picarro analyzers:

* Superb sensitivity, precision & accuracy with virtually no drift
* Fast, continuous, real time measurements without interference
* Large dynamic range with high linearity
* Field and laboratory deployable with no consumables
* Installed and operational in minutes
* Rugged and insensitive to changes in ambient temperature

The gas stream contains ammonia, nitrogen oxides and in some cases sulfur dioxide . The NOx analyzer is a UV diode array process analyzer. Measuring the complete spectrum of the stream continuously and instantaneously.

The full spectrum advantage
The figures below show the absorbance spectra of the DeNOx process stream components,. The absorbance features overlap, therefore, a full high resolution spectral analysis is essential. High accuracies at a relatively wide dynamic range can be achieved due to the sharp absorbance features of the DeNOx stream component

The system uses an aspirator driven extractive sampling system with a heated umbilical sample line. The sample flows through the absorption cell and the oxygen sensor in series. Long sample lines are avoided, minimizing the normal sample losses associated with sample adhesion to interior tubing walls.
