Locate Natural Gas Leaks with Unmatched Sensitivity, Ease-of-Use, and Thermogenic vs. Biogenic Discrimination
Introducing the MIRA LDS analyzer, a high sensitivity natural gas leak detection system from Aeris Technologies, Inc. The MIRA LDS combines a breakthrough, real-time laser absorption spectrometer with built-in GPS capability to produce the world’s smallest, most powerful natural gas leak-mapping tool.
The MIRA LDS analyzer operates in the mid-IR, achieving unparalleled, simultaneous methane and ethane sensitivity at the ppb per second level. Natural gas is thus unambiguously discriminated from other biogenic sources such as landfill gas, cattle operations, swamp gas, sewer gas, and permafrost. The MIRA LDS analyzer provides a discrimination capability unique on the market at a fraction of the size and the price of other laser-based analyzer in its category, eliminating false alarms and enabling accurate ethane/methane ratio data in real-time. The MIRA LDS analyzers provide accurate ethane/methane ratios at levels rivaling mass spectrometric methods, without requiring any sample handling or consumable columns.
The MIRA LDS analyzer includes a GPS acquiring spatial coordinates every second. The instrument aggregates those coordinates to the rest of the measured parameters in a spreadsheet file. In addition, a colorized KML file is continuously updated and can be open directly in Google EarthTM to map the measurements with unprecedented ease. The MIRA LDS analyzer can be operated at highway speed, enabling to survey natural gas infrastructure at a speed and efficiency never seen before.
Green = no significant methane ethane correlation
Red = significant methane ethane correlation thus natural gas is in the air!
