- CO2 delta oxygen 18 isotope (δ18O).
Acoem Spectronus™ (formerly known as the Ecotech Spectronus™) is the only high accuracy multispecies trace greenhouse gas and isotope analyser based on Fourier Transform Infrared (FTIR) spectroscopy.
Originally conceived by Professor David Griffith and his team at the University of Wollongong, Spectronus™ has been used for a variety of applications by researchers around the world for nearly two decades, providing precision values for greenhouse gas measurement that exceed World Meteorological Organisation (WMO) standards.
ICOS network approved
The SpectronusTM is ICOS network approved as an ICOS compliant greenhouse gas analyser. The ICOS Research Infrastructure was created to establish a sustainable greenhouse gas observation system that provides a framework for high quality climate change research and increases the usability of research data.
Application Examples of SpectronusTM
- Amazon Jungle
- Antarctica & the Southern Oceans
- Next generation design

Amazon Jungle – High tower climate research
Dr Hella van Asperen, from the Institute of Environmental Physics at the University of Bremen (Germany) in the Amazon Rainforest, Brazil, decided to investigate broader applications for her preferred instrument, the SpectronusTM analyser.
Inspired by her previous research in Germany, Denmark and Italy, Dr Hella can Asperen (pictured above) set her sights on building up a long-term measurement campaign of concentrations and flux emissions of methane and other gases in the Amazon Rainforest using the SpectronusTM.
Antarctica & the Southern Oceans – Aerosol gases in clean atmosphere research
Acoem’s SpectronusTM gas analyser is an integral part of an Australian multi-university research project to study how aerosol gases form in clean atmospheres. Beginning in November 2018, the Spectronus TM – the first multispecies greenhouse and other trace gases analyser – will be on board Australia’s Antarctic icebreaker, the Aurora Australis, as it cruises the Southern Ocean from Hobart to various Antarctic and sub-Antarctic stations.
Continuous development – Next generation Spectronus™ available now
Until recently, Spectronus™ was predominantly utilised in research applications, however Acoem recognised that there was a demand by environmental agencies and key industries for an analyser that could be used to measure multiple greenhouse gases and their isotopes together, with one piece of software, one set of calibrations, ease of operation and a competitive total cost of ownership.
To cater for more diverse markets, Acoem has developed a new, more flexible version of the Spectronus™ that puts accurate greenhouse gas and isotope measurement within everyone’s reach. Its user friendliness, rack mountable configuration and language options have been improved to further enhance the already accurate and functional analyser.
