Freon affects infrared gas monitors

Gas Chromatography monitors Green House Gas (GHG) emission from flares

A considerable contribution to the worlds total GHG emission originates from gas flaring: According to a World Bank estimation an amount of around 150 billion cubic meters of natural gas is flared around the world annually, contaminating the environment with 400 million tons of CO2. This is equivalent to around 25 % of the United States’ gas consumption, or 30 % of gas consumption in the Europe...

Infrared gas sensor

This paper proposes a new measurement scheme of gas concentration by infrared sensor, for high accuracy measurement of gas concentration and safety protection. Furthermore, the principle of infrared absorption, test methods and optical chamber structure are expounded. And a double-beam differential detection system is designed. The paper key to introduce the software and hardware design of infr...

Infrared Gas Sensor

Gas imaging by infrared gas-correlation spectrometry.

We describe a new method for visualization of gas flows based on infrared absorption and gas-correlation techniques. This result is a gray-scale or false color-coded image showing the distribution of a specific gas in the area studied. A sequence of images showing the workplace test setup with a turbulent flowing gas is presented.

Characterizing Supersonic Gas Jet-based Beam Profile Monitors

The next generation of high power, high intensity accelerators requires non-invasive diagnostics, particularly beam profile monitors. Residual gas-based diagnostics such as ionization beam profile or beam induced fluorescence monitors have been used to replace commonly used scintillating screens. At the Cockcroft Institute an alternative technique using a supersonic gas jet, shaped into a 45 cu...
