Natural Gas: Complete Analytical Solution
Chromatotec® has developed in its Research & Development laboratories, a new instrument for hydrocarbon (C1-C6+) measurements and calorific values as well as WOBBE index computation. 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 ...

Accuracy in temperature sensor response time estimation for new nuclear reactor designs
One method for measuring the response time of temperature sensors, the plunge test, verifies that the sensor has a suitable response time in the laboratory before installation. However, plunge test results cannot be extrapolated to the response time in an operating plant because response time is affected by multiple factors such as the ratio of internal heat-transfer resistance to the surface ...

Servomex Plasma Emission Technology: A leap forward in the accurate, safe and costeffective measurement of UHP gases
In the field of gas chromatography, many sensors are available that cover a broad range of measurements. 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. However, ...
