Methane & Hydrogen Sulfide Analyzer - Model G2204

The G2204 is a fast Cavity Ring-Down Spectrometer that, when coupled with the optional A0941 Mobile Kit, is ideal for creating real-time visual plume maps of fugitive emissions of methane and hydrogen sulfide. The G2204 can be ordered separately, as a stand-alone analyzer, or with a complete turnkey kit that enables real-time plume mapping. You can go from opening a box to posting Google Maps of plumes in less than an hour.

• The complete kit is the only product that delivers real-time Google Earth plume maps of landfills, pipelines, refineries, paper mills 
• Beyond-the-fenceline mapping, can identify plume origin down to individual buildings or smokestacks
• Provides precise targeting for air bottle captures
• Extremely fast and accurate - continuous readings even at 65 mph with 30 readings per minute
• Shock and vibration resistant: deployable in cars, trucks and boats

This breakthrough mobile-ready system maps emissions plumes of methane and hydrogen sulfide back to point of origin at parts-per-billion concentrations even while driving at freeway speeds. For the first time ever, scientists and non-scientists alike can perform detailed beyond-the-fenceline emissions mapping to spot plumes of methane and hydrogen sulfide from landfills, pipelines, refineries, paper mills or industrial plants. For air quality and environmental experts, the Picarro plume mapping system can dramatically improve targeting for air bottle captures used to detect plumes of volatile organic compounds (VOCs) such as benzene, xylene, and tolulene (These VOCs sometimes are associated with methane). Large emitters and industrial companies can use the Picarro plume map tool to map uncontrolled emissions in order to spot process inefficiencies.

A powerful greenhouse gas, methane is also a compound of great interest to entities seeking to reduce their contribution to global warming. Toxic hydrogen sulfide is another compound of interest for air quality and environmental regulators. Natural emissions of both methane and hydrogen sulfide are also a key environmental consideration in geologically and volcanically active portions of the Earth. Grid patterned surveys with the system can yield detailed plume maps for cities, towns and wide-area regions such as very large landfills. The analyzer system can also operate in a small plane or boat for aerial or marine mapping operations. It is vibration and shock resistant and unaffected by wide temperature, pressure and humidity swings. This mobile, real-time plume mapping capability is unique to Picarro.

The plume mapping system uses Picarro's powerful and high-precision time-based Cavity Ring-Down Spectroscopy (CRDS) analyzer. Picarro's unique CRDS analyzer is a time-based measurement system that uses a near-infrared laser to quantify spectral features of molecules in a sample gas passed through an optical measurement cavity. An effective path length of up to 20 kilometers inside the cavity results in exceptional instrument precision and sensitivity. Picarro analyzers use a small 35 cc volume cavity, ensuring better temperature stability, faster gas exchange, lower noise and higher sensitivity. Precise cavity temperature controls (better than 0.002 deg. C) and pressure control (better than 0.003% of an atmosphere) designed into the system ensure accurate measurements over very long periods of time. As a result, Picarro systems maintain high linearity, precision, and accuracy with minimal calibration. Picarro CRDS systems all include a patented, high-precision wavelength monitor that makes certain the analyzer only monitors spectral features of interest. This virtually eliminates spectral "noise" from interfering species, such as combustion byproducts like CO. 

The Picarro plume mapping kit includes a mobile weather station, backup bateries, gas sample tubing, a GPS system, an inverter, a netbook PC and appropriate cables for quick set up. The system can be installed easily on a vehicle or as a stationary monitor. A customer-provided mobile broadband connection is required for viewing the data in real time on Google Earth. The analyzer can be ordered with rack-mounts for stability in vehicles. The system is controlled using intuitive GUI software tools included on the CPU of all Picarro analyzers and on the included netbook PC. (Customers will need to supply a monitor for real-time viewing A wireless Internet broadband card will also be required for real-time streaming and Google Maps streaming image display.)

Picarro's diagnostic software suite continuously measures and records 38 parameters for rigorous quality control and assurance of data integrity. If an analyzer is connected to the Internet, Picarro's service organization can access it remotely, practically anywhere to provide rapid support and problem resolution. Users can connect remotely and control the analyzer through a standard Remote Desktop connection or with similar remote login software. 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 and via optional analog outputs. Only Picarro delivers this unparalleled combination of high-precision and accuracy, ease of use and installation and real-time mapping in a rugged, mobile-ready package.
