5 Signs Your Gas Analyser Is Letting You Down
Gas analysers are expected to run continuously, often in demanding industrial environments, providing accurate and reliable data day after day. Most of the time, they do exactly that. But like any precision instrument, their performance can degrade – and the signs that something is wrong are not always obvious. The most common measurement problems don’t […]
Complete Guide to Gas Sampling System Design
Accurate gas analysis depends on far more than the analyser itself. Before any measurement takes place, a representative sample of the process gas must be extracted, conditioned, and delivered to the instrument in a controlled, reliable way. This is the sampling system — and it is one of the most overlooked aspects of gas measurement […]
Continuous VOC Monitoring for Thermal Oxidisers: Real-World Benefits
In solvent-based manufacturing, emissions control is not simply a compliance exercise. It directly affects process stability, operating efficiency, environmental performance and production confidence. For facilities using Regenerative Thermal Oxidisers (RTOs) to abate Volatile Organic Compounds (VOCs), continuous monitoring provides the real-time data needed to confirm that emissions are being correctly treated – not just during annual compliance […]
Counting the cost of unreliable gas analysers
Back in 1977 when Signal Group first started manufacturing gas analysers, components were less proficient and consistent, and analysers required a higher level of ‘tender loving care’. At that time, James Clements, the company’s Managing Director, was little more than a twinkle in his father’s eye, but today, with an engineering degree and over 23 […]
How Santa’s Workshop Became Emissions-Compliant with the Solar CEMNEX
The surprising story of how the North Pole turned to advanced gas analysis to keep Christmas clean and green. For centuries, Santa’s Workshop has been celebrated as one of the most productive manufacturing facilities on Earth. With millions of toys produced annually, an entirely renewable transport fleet powered by reindeer, and a workforce of highly […]
Multiplexed gas analysers can lower costs
Just as a puppy is not just for Christmas, a gas analyser is not just for regulatory compliance. Process managers generally install a continuous emissions monitoring system (CEMS) because they have to, by law. In the following article, James Clements, MD at Signal Group, explains how businesses can extract maximum value from an investment in […]
Sustainable packaging can be a bit like ‘whack-a-mole’
Gas analysers are performing a vital role for packaging manufacturers looking to check the environmental performance of their latest products as they seek new ways to develop sustainable packaging. Signal Group, the UK based manufacturer of gas analysers, has seen a particular increase in demand for its continuous VOC measurement instruments in the packaging sector. […]
Why Certification Matters in VOC Monitoring – MCERTS, EN14181 & EN15267 Explained
When monitoring volatile organic compounds (VOCs) and total hydrocarbons (THC) in regulated industries, accuracy isn’t optional — it’s a legal and operational necessity. Whether you’re managing a waste incinerator, a thermal oxidiser, or a medium combustion plant, your gas analysis system must meet strict performance and certification standards. At Signal Group, we’ve engineered the SOLAR CEMNEX to not only deliver world-class VOC measurement but to […]
Signal Group launches new MCERTS approved VOC emissions monitor
Signal Group, a leading UK manufacturer of gas analysers, has announced the launch of SOLAR CEMNEX, a continuous emissions monitoring (CEM) system with MCERTS approval for the measurement of total organic carbon concentration in sample gas. Designed for regulatory compliance and process control, employing a reference method flame ionisation detector (FID), the new analyser will […]
Inside the Heated Sample Line: Why Temperature Integrity Matters in Gas Analysis
In the realm of precise gas analysis, particularly within continuous emissions monitoring systems (CEMS) and process control applications, the integrity of the sample from the point of extraction to the analyser is paramount. A critical, yet often underestimated, component in maintaining this integrity is the heated sample line. Failure to control the sample gas temperature […]
