Introduction In industries around the world, precision gas analysis plays a vital role in maintaining product quality, ensuring safety, and meeting compliance standards. Cambridge Sensotec designs and manufactures international gas analysers that operate across a wide range of global applications. From manufacturing and energy to pharmaceuticals and aerospace, organisations depend on these ...
Accurate calibration in gas chromatography transforms good measurements into precise, actionable data. When handling high-stakes tasks in environmental science or pharmaceuticals, ensuring calibration at parts per billion (ppb) becomes non-negotiable. This article will show you how ppb-level calibration standards sharpen gas chromatography’s capabilities and why they matter in your ...
Environmental protection and monitoring are crucial to maintaining the ecological balance of the earth. Continuous Emission Monitoring Systems (CEMS) play a key role in this area, monitoring pollutants in the atmosphere in real time to ensure that businesses and governments comply with emission standards. This article will compare several CEMS methods with different principles, explore their ...
Oceanic trace gas analysis is a vital tool for understanding the complex relationship between the Earth’s oceans and its atmosphere. ...
To carry out accurate trace gas analysis, it’s essential that trace level gas calibration is carried out regularly and with precisely prepared calibration gas mixtures. In this blog post, we explore the basics of trace gas analysis and take ...
Trace level gases are those that are present in small concentrations, such as one ppb or lower. ...
From SIFT to ultimate performance PTR-TOF trace gas analyzers The success story of PTR-TOFMS has its roots in the so-called “Flowing Afterglow Technique”, introduced in the 1960s. ...
Researchers in the Australian Antarctic Science project collected aerosol data above the Southern Ocean to improve their understanding of the connection between clouds and climate change. Evaporation and condensation are the basic concepts leading to cloud formation; however, many factors impact the end results. In general, as water vapor molecules rise from the surface of the Earth, they ...
Celebrating the “Gold Standard” for Real-Time Trace Gas Analysis On July 14, 1998, our company was founded by a group of dedicated scientists and entrepreneurs. ...
Starring the IONICON team and our guests who toured through our company in small groups, getting some real hands-on when learning about PTR-MS, real-time trace gas analysis in comparison to traditional methods and analytical instrument development. ...
In particular the sensitivity of the instrument has been improved markedly to allow detection of trace metals down to the part per billion (ppb) level. This capability is particularly important to power generators using liquid fuel, as high levels of alkali metals in the fuel can corrode expensive turbines resulting in costly damage and downtime. The significant performance ...
Westwood’s biogas averages 60 percent methane (CH4), 40 percent carbon dioxide (CO2), about one percent oxygen (O2) with hydrogen sulphide (H2S) at trace levels below 100ppm. The static gas analysis unit is set to take a biogas reading every five minutes, 288 times a day. ...
In the question/answer session below he informs us on how smooth the transaction was from initial enquiry to install at his laboratory and explains the benefits of using Peak Precision Hydrogen Trace 250 gas generators in his analysis. Typically, what is the focus of your GC analysis - what sort of applications? ...

Historically, the technique has been used for a broad range of applications from the composition of gas and liquid mixtures to the analysis of trace components for gas purity analysis. In cases where a well-defined method of analysis is involved, such as the measurement of combustion gases for ...
Virtually all chromatographs, however, are designed for the analysis of liquid samples. This design characteristic causes problems for the gas analyst, as instrumental sensitivities are typically below that required for trace-level analytical work on gaseous samples, not to mention the modification of hardware which is required before ...
