Setting the standard: Stack Testing industry redefined by GT6000 Mobilis

Gasmet Technologies: How about replacing intensive manual sampling methods x11 with just one continuously measuring analyzer? Stack testers can now replace and complement a large variety of methods with one certified gas analyzer - The Gasmet GT6000 Mobilis.

Certifying the FTIR technology to meet the requirements and to ensure accuracy

Every major industrial facility emitting significant airborne emissions has a Continuous Emissions Monitoring system (CEMS) to measure that emission limit values are not breached. But how do we know the CEMS is measuring correctly for its lifetime of ten plus years?

Quality Assurance Level test, typically referred as QAL2 tests and annual surveillance tests (AST) are done in Europe and many parts of Asia by third party expert test laboratories, typically referred as “stack testers". They compare the readings of the CEMS to the ones produced by proven test methods, thus proving the CEMS is performing as it should.

The stack testers can use standard reference methods that are often manual. Moreover, alternative methods, like portable automated measuring systems (P-AMS), can be used if they are proven to provide equivalent results. But how to prove the equivalence? 

Not just a milestone, but a testament of Gasmet’s quality and commitment

EN standard EN 15267-4 was written in 2017 for the purpose of certifying portable multi-gas analyzers for stack testing. The standard includes extensive tests first in the laboratory and later in the field at least in at least 5 different industrial sites.

During the testing process, you need to measure linearity, interferences, effect of temperature, effect of vibrations, field usage and many other parameters. And each gas you plan to have certified will need to be tested separately! For systems that measure a lot of gases, getting the certificate is a project for several years - on top of developing the actual analyzer of course.

FTIR is the most common CEMS method in demanding environments such as waste-to-energy plants or cement kilns. However, no QAL1-certified FTIR P-AMS existed even after seven years following the standard introduction - showing how tight the requirements are for systems that measure 10+ gases. At Gasmet, we decided to become the company that breaks the limit. After several years of hard work, here we are.

GT6000 Mobilis is the world's first QAL1-certified FTIR P-AMS

The GT6000 Mobilis analyzer is specifically designed for portable use, handling varying gas matrices, frequent assembly and dismantling, and the demands of moving between sites.

Equipped with the ability to measure some of the most important gaseous emission compounds and boasting some of the lowest limits for compliance measurement, the GT6000 Mobilis guarantees precise and reliable results immediately on-site.

Its advanced capabilities and wireless connectivity options ensure flexible usage and remote operation, empowering stack testers with one flexible method for multiple gases and reducing the need for supplementary methods.
