Our range of methane gas analyzers provides accurate monitoring of CH4 in your process, using a variety of sensing technologies to deliver the best measurement results for each application. We offer the SERVOTOUGH SpectraExact 2500 and Laser 3 Plus Combustion as hazardous area methane testers, and a number of safe area SERVOPRO analyzers for industrial gas and purity applications. These include the MultiExact 4100, MultiExact 4200, HFID, Chroma, NanoChrome, and NanoChrome ULTRA gas analyzers. For CEMS applications, we have the 4900 Multigas, rounding off a comprehensive set of solutions for methane gas analysis.
Methane is a hydrocarbon, and the main constituent of natural gas. As a greenhouse gas, methane emissions must be monitored in industrial processes to meet regulatory requirements. Monitoring methane in combustion is also an important safety measure. It is also key to safety and process efficiency in a number of industrial processes, including ethylene and EDC manufacture. Additionally, methane can contaminate high-purity gases needed for medical or industrial use, so must be monitored at trace and ultra-trace levels to ensure gas quality.
Fired heaters running in a steady state are very safe, and can be trimmed and controlled by measuring oxygen and combustible concentrations. However, changes to the ambient conditions, fuel composition, or pressure regulation can snuff out the flame or alter its profile to become heavily fuel-rich. These changes can create a pocket of methane on a bank of two or three burners, inside a working process. Normally undetected by point measurements, this potentially leads to a flood of methane coming up through the process. By measuring methane across the process using a Tunable Diode Laser analyzer – such as the SERVOTOUGH Laser 3 Plus Combustion – a bank or array of burners going out can be rapidly detected, allowing immediate corrective action.
Several sensing technologies are available to measure methane. The most appropriate solution depends on the application, and the measurement range required.
We support many applications with methane gas analysis solutions, ranging from power generation and hydrocarbon processing (HP) to medical gas purity and semiconductor gas quality. For power, HP, and emissions, our methane analyzers include the SERVOTOUGH SpectraExact 2500 and SERVOPRO analyzers such as the MultiExact 4100, MultiExact 4200, HFID, and 4900 Multigas. These methane gas analyzers use Gas Filter Correlation or Flame Ionization Detector sensing to measure CH4. For the trace and ultra-trace measurements of methane required by industrial, medical, and UHP gases, Gas Chromatography and Plasma sensing technologies are required. We provide the Chroma, NanoChrome, and NanoChrome ULTRA analyzers.
The 4900 Multigas is a high-performance CEMS analyzer designed for a wide range of multi-gas measurements.
The Chroma is optimized to specific background gases to ensure optimum performance for your application.
Utilizes an internally heated oven set to 190°C (374°F) to maintain the sample gas above its dew point, for optimum performance in total hydrocarbon analysis (THC).
Unmatched installation flexibility plus cost and performance benefits, ready for fast, accurate and responsive measurements in combustion and process control.
A high-performance multi-gas analyzer designed to provide up to four simultaneous gas stream measurements.
The MultiExact 4200 analyzes up to four gases simultaneously for Syngas and HyCO
Incorporating the latest advances in gas sensing and signal processing methodology, the NanoChrome revolutionizes ultra-trace purity measurements.
Using proven ultra-trace sensing, the NanoChrome ULTRA conquers the most stringent demands of the semiconductor industry, delivering a cost-effective solution compared to competing technologies.
A getter-based purification unit designed for the purification of carrier gases used in Gas Chromatography (GC) and other analytical applications
Flexible single and multicomponent gas analysis capability for corrosive, toxic and flammable sample streams.
Our methane analyzer range uses proven sensing solutions that deliver accuracy, ease of use, and a long operational life.
Flammable hydrocarbon samples can be measured at very low levels with our Flame Ionization Detector (FID) sensors. Based around the detection of ions formed by combustion, they are key to the sensitive, accurate measurements delivered by our SERVOPRO Chroma, FID, and HFID analyzers. It must be combined with a non-methane cutter assembly to measure methane concentrations.
Gas Chromatography is an analysis technique that works effectively alongside other sensing technologies, delivering a highly sensitive measurement of the constituent components of a gas sample. It is used in our SERVOPRO Chroma, NanoChrome, and NanoChrome ULTRA analyzers.
An advanced form of Infrared sensing, Gas Filter Correlation (GFC) technology is ideal in applications with interferent background gases, delivering precise, sensitive measurements. It is used in our SERVOTOUGH SpectraExact 2500 photometric analyzer, and is a key technology for our SERVOPRO multi-gas analyzers, the MultiExact 4100, MultiExact 4200, and 4900 Multigas.
Developed to provide a safer alternative to flame-based sensing for hydrocarbon analysis, Servomex’s Plasma emission detection technology delivers ultra-low gas measurements. It is used in our SERVOPRO Plasma, Chroma, NanoChrome, and NanoChrome ULTRA analyzers.
Tunable Diode Laser (TDL) technology offers a fast-response, accurate measurement that is highly specific to the gas of interest. This non-contact, non-depleting sensing is used in our innovative, compact SERVOTOUGH Laser 3 Plus range of analyzers.
