MIRICO and NPL Awarded Innovate UK Project to Test Laser Dispersion Spectroscopy

MIRICO, in collaboration with the National Physical Laboratory (NPL), were successful in obtaining a £285k Innovate UK award to carry out a series of laboratory and field validation trials on MIRICO’s Laser Dispersion Spectrometer instrument. This will be an independent demonstration of the instrument’s capabilities in both remote open path sensing and in-situ extractive gas analysis utilising NPL’s advanced testing facilities.

The trend towards increasingly sophisticated industrial processes and growing concerns on environmental pollution and its adverse impact on human health has brought about an urgent need to improve measurements of key chemical species. For a truly sustainable reduction in emissions and accurate estimates of emission rates, instruments must provide highly sensitive, precise and accurate data and yet be versatile and practical for use in the demanding conditions expected when they are deployed in the field.

MIRICO’s Laser Dispersion Spectroscopy technique was developed to meet the above requirements  in real time and in demanding environments. The system offers unique features that have been tested in real world applications, and will now be further tested to a high level of traceability using NPL’s  detailed analysis facilities and expertise that NPL’s team can offer.

MIRICO’s novel technology will be tested against traceable reference standards developed by NPL under controlled environments. The first series of trials are commenced the week starting 23rd October 2017 and are testing our open path product for methane detection.

NPL will set up a series of diffuse releases to simulate different emission sources including leaks, ground diffuse emission and stack emissions under controlled conditions. This will be done using NPL’s controlled release facility. The objective of these trials will be to demonstrate MIRICO’s instrument capability in accurately identifying and reporting such sources, as well as analysing instrument specifications including response time, detection limit, precision, and other measurement parameters.

The second series of trials will test MIRICO’s in-situ extractive gas analyser using NPL’s Tunable Rapid Atmosphere Controlled Environment (TRACE) facility and specially developed stable primary standard reference gas mixtures. The key objectives of these trials will be to demonstrate MIRICO’s LDS 100 EGA ability to measure trace levels of ammonia as well as determining other core instrumental parameters,  to enhance its measurement capabilities..

The output of the project will directly feed into MIRICO’s product development, further improving their measurement capabilities, whilst also providing an independent demonstrations of the technology in a variety of applications, thereby facilitating entry into the atmospheric science, oil and gas, and semiconductor fabrication markets.
