Temperature-Programmed Reaction (TPRx) offers essential insight into how catalysts behave during temperature ramps. By observing the gases released or consumed during controlled heating, researchers can determine activation temperatures, identify reaction pathways, and evaluate material stability. The quality of the information derived from TPRx depends on the performance of the detector used to ...
The device also uses NDIR technology to analyse carbon monoxide, carbon dioxide and methane up to 100%, while hydrogen is measured up to 100% using a thermal conductivity detector. Hydrogen sulphide can also be measured in a range from 0 to 50 ppm or up to 2000 ppm. ...
Hydrogen is playing an increasingly important role in the energy and industrial sectors, thanks to its potential as a clean energy source and its use in various manufacturing processes. However, hydrogen’s unique properties—especially its flammability and ability to leak easily—make accurate hydrogen gas measurement crucial for ensuring safety in any environment where it is ...
Hydrogen is increasingly becoming a key player in the transition to cleaner energy solutions, especially in industries focused on renewable energy, manufacturing, and transport. Due to its unique properties, measuring hydrogen accurately is crucial for ensuring safety, efficiency, and compliance in various applications. In this blog, we’ll explore how to measure hydrogen effectively, the ...
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 ...
In the modern industrial production process, especially in the fields of chemical industry, petroleum and energy, the generation and application of synthesis gas (“syngas” for short) occupies an indispensable position. Synthesis gas is a mixed gas composed of carbon monoxide, hydrogen and other gas components. It is widely used in many fields such as chemical raw materials, energy ...
Introduction In the current climate change environment, finding clean energy alternatives to traditional fossil fuels has become crucial. Biomass gasification technology has become a high-profile energy production method, which converts biomass waste into syngas that can be used for power generation, heating and fuel production. However, to use this technology effectively we need to accurately ...

Here we will offer a breakdown of some of the key market segments that we serve. ...
Jeff Sherman, Vice President, Business Development, Micromeritics The ICCS incorporates mass flow controllers for fully automated precise gas control and a cold trap for the removal of condensable vapors. A precision thermal conductivity detector monitors changes in the concentration of gases flowing into and out of the sample reactor. ...
Each of those sensors has advantages and drawbacks, so a solid understanding of the different technologies is important. Thermal Conductivity (TCD) and Flame Ionisation Detector (FID) sensors have been available for decades and are the most commonly used measurement technologies. ...
Gas chromatography is a novel technique for separating and quantitating vaporized compounds using an inert carrier gas. It operates on similar principles to column permeation chromatography, where a sample is dissolved in a liquid phase and passed through a porous stationary structure. Compounds are characterized and quantified by the time it takes for them to elute from the permeable, packed ...
This analyzer is based on chromatography principle using a Thermal Conductivity Detector (TCD). The sample will be separated into the column and quantified by the detector. A difference of thermal conductivity between the reference gas (carrier gas) and the sample gas will allow the ...
The estimation method presented here can be used to extrapolate laboratory response-time measurements to determine sensor response time in another medium, in different test conditions, or in actual applications such as a nuclear power plant. However, experiments conducted at Oak Ridge National Laboratory have confirmed that the effect of temperature on sensor response time cannot ...
Hogan*Texas Instruments, Inc.Dallas, TX 75265 Low ppb detection limits for contamination in cylinder gases have been achieved with gas chromatography using a modified gas injection system and megabore capillary columns with a variety of detectors including mass spectrometry, atomic emissions, and discharge ionization. ...
