Financial risk at stake with your LNG quality measurement system.

EffecTech

Measurements of gas and liquid natural gas (LNG) quality, along with flow measurements, ultimately determine the commercial value of the gas and LNG, which is vital for the long-term successful operation of a custody transfer / fiscal measurement system. The linearity of these instruments can lead to errors which contribute to the measurement uncertainty.

Hydrogen Safety in the Laboratory

Bruce Peat, Peak Scientific

Original blog written by Bruce Peat, Peak Scientific. Posted 02/03/16: http://www.peakscientific.com/blog/h2-safety/

The scientific community in China has been shocked by an accident in a laboratory at the prestigious Tsinghua University in Beijing, where it is believed that an explosion, and resulting fire, from bulk supplied hydrogen gas being used in the lab caused the death of a post doctorate researcher.

Q & A: on Calibration & Bump/Response Testing of Gas Detection Instruments

Greg Shires

A question and answer session with Greg Shires, Managing Director of CAC GAS & Instrumentation.

First let me by clear on this subject: Gas detection instruments are life saving devices.  

They can make the difference between a worker going home at night or not. If I was required to use a gas detection instrument in my work place each day I would make sure it was calibrated weekly and bump tested prior to every use. This would make sure it was accurate and I was safe.

So, let’s discuss this further.

General Rules for Designing Custom Gas Mixtures

Paul Fry

We are often asked for many different gases for the same applications. When possible, the required gases can be combined into the same cylinder to reduce the overall gas cost. When creating custom gas mixtures you must be aware of potential issues from mixing different compounds together.
