Los Gatos Research (LGR), the leader in precision trace gas analyzers, announced that it has expanded the high speed (10 Hz) trace gas analyzer line to include as many as seven different trace gases with various combinations available in eight different products. The trace gases that can be measured include carbon dioxide (CO2), water vapor (H2O), carbon monoxide (CO), methane (CH4), nitrous oxide (N2O), ammonia (NH3), and carbonyl sulfide (OCS or COS). These analyzers can connect them to an existing data logger or can connect to an (optional) LGR Multi-Channel Data Logging System that synchronizes serial (RS-232) outputs from a single or multiple LGR analyzers and other devices such as GPS or sonic anemometers and records all data with a common time stamp.
"Our high speed, high precision analyzers can save tens of thousands of dollars over other alternatives and include fully automated operation, and Ethernet and wireless connectivity. They provide a tremendous flexibility for eddy covariance researchers since they are designed to be deployed in unmanned monitoring stations where many of these trace gases have never been measured before," says Dr. Douglas Baer, President of LGR.
LGR high speed and high precision gas analyzers are based on the company's patented technology, a fourth-generation, cavity-enhanced laser absorption spectroscopy technique. This unique approach is both more rugged and more precise than earlier cavity-enhanced techniques, such as conventional cavity ringdown spectroscopy, because LGR instruments do not need ultra-precise alignment or sub nanometer stability of its optics, or a high degree of thermal control. This ensures higher absolute accuracy, longer maintenance intervals, higher reliability, and reduced cost of ownership.
