Greenhouse Gases
Climate change has gained significant interest over the past few decades and the monitoring of a number of different gases and aerosols is now being performed on a regular basis and around the world.
Ecotech is the region's specialist in greenhouse gas monitoring.
In a joint collaboration between Ecotech and the University of Wollongong, Ecotech is now manufacturing the world's only FTIR based instrument that meets GAW precision specifications for greenhouse gases which include CO2, CO, NO2, H2O and their isotopes.
Ecotech is also the exclusive distributor of the Los Gatos Research range of greenhouse gas monitors, which are being used by the CSIRO Division of Atmospheric Science as well as many other atmospheric research organisations around the world.

Designed for the precise measurement of trace gases and isotopes in ambient air including the full range of greenhouse gases.
Ecotech's latest analyser combines a Fourier Transform Infrared (FTIR) spectrometer, multi-pass gas sample cell and a high performance detector with sophisticated software for fully automated operation and real-time quantitative analysis of trace gases in air or other gas mixtures. It provides high repeatability and excellent reproducibility for multiple gas species simultaneously without the need for frequent gas calibrations.

Since 1994, LGR has been developing innovative laser-based measurement strategies for non-destructive analyses of gases, liquids and solids. Building on advanced education in Physics, Chemistry and Engineering from the finest universities worldwide, followed by over 120 years of cumulative real-world experience in product development and applied research, LGR's Senior Staff has demonstrated expertise in the areas of optical diagnostics, laser spectroscopy, physical chemistry, and chemical physics. In addition, LGR holds key patents that are basic to the development and application of LGR's technologies.
LGR's analysers use LGR’s patented Off-axis ICOS technology, the fourth-generation cavity enhanced absorption technique, which employs a high-finesse optical cavity as the measurement cell. LGR’s technology has many proven advantages over conventional first-generation cavity ringdown spectroscopy (CRDS) techniques. In brief, since the laser beam does not have to be resonantly coupled to the measurement cell (i.e. precise beam alignment is not critical), LGR Analyzers are relatively inexpensive, simple to build, and inherently robust thermally and mechanically. In addition, since LGR’s technology can record reliable absorption spectra over a far wider range of optical depths (absorbance values) compared with CRDS, LGR Analyzers provide measurements over a much wider range of mixing ratios (gas concentrations). Finally, due to the ease and simplicity of recording and quantifying the measured spectra using LGR’s Off-Axis ICOS, LGR Analyzers display the entire absorption spectra to the user in real time allowing for immediate system diagnostics and performance validation.
