ABB Ability™ Stationary gas emissions monitoring solution


EverGuard™ provides continuous, ultrasensitive monitoring of natural gas emissions near high-risk areas.


A robust and sensitive solution

EverGuard™ consists of ABB’s renowned microportable multi-gas analyzer (GLA131 Series) embedded into a weatherproof NEMA 4X enclosure that can be connected to several optional modules (e.g., solar panel, uninterruptible power supply, cellular transmitter, Wi-Fi router, GNNS receiver, weather station, multi-inlet sampling manifold) to meet the most stringent requirements of almost any application requiring continuous monitoring of natural gas leaks.

  • Continuous gas concentration measurements anywhere
  • Fast response rate enables rapid alarm response
  • No cross interference
  • Highest sensitivity measurements allow detection far from leak source
  • Low power requirements facilitate solar power operation
  • Inherently rugged technology proven worldwide
  • Cyber secure internet connectivity
  • Highest reliability
  • Simple to service

EverGuard™ applications

This comprehensive gas leak detection solution was designed for the most critical applications, including:

  • Upstream installations: well pads and storage
  • Midstream distribution network: gathering lines and pipelines
  • Downstream facilities: factories, distribution stations and storage facilities
  • High-risk zones: public gathering areas, schools, hospitals

The LGR-ICOSTM advantage

The inherent advantages of OA-ICOSTM technology make LGR trace gas and stable isotope analyzers the best choice, whatever the application.
  • Parts-Per-Billion (ppb) Precision: OA-ICOS avoids the expense and vulnerability of a sub-nanometer opto-mechanical setup. This enables it to easily deliver parts-per-billion precision (or better) quickly and in an easy-to-use package.
  • Wider Dynamic Range: OA-ICOS directly measures absorption rather than only a cavity decay time. Therefore it offers a linear response over a significantly wider dynamic range than conventional CRDS (i.e. up to 100% mole fraction for some gases).
  • Best Performance: OA-ICOS analyzer performance is not dependent on hyper-critical optical alignment, whereas older cavity-based techniques (e.g., CRDS) require sub-nanometer optical component alignment. This makes these older techniques very vulnerable to degraded performance due to vibrations, small physical shocks, and changes in temperature and pressure.
  • Field Serviced: OA-ICOS performance is orders of magnitude less sensitive to internal alignment, so our rugged instruments are robust and reliable. And designed with simplicity in mind, in the rare instance that repair is necessary; LGR instruments may be easily serviced on site by anyone.
  • Lower Manufacturing Cost: OA-ICOS analyzer performance is not dependent on hyper-critical optical alignment, whereas older, conventional CRDS techniques require sub-nanometer optical component alignment. This necessitates the use of expensive electro-mechanical components and complex feedback loops as well as very time-consuming cleanroom assembly and elaborate testing.
  • Better Value: OA-ICOS analyzer performance is completely unaffected by any minor shifts in optical alignment. This enables the use of simpler, lower-cost components and fewer feedback control systems, as well as simplifying our assembly process.
  • Minimal Downtime: OA-ICOS technology does not require ultra-precise optical alignment. This means that a minimally trained user can easily remove a cavity mirror, if necessary, and then clean and replace it in only minutes, with no impact on performance or expensive returns to the factory.
