How Residual Gas Analysis (RGA) Factors into Leak Detection
Leak detection is an essential aspect of vacuum operations, underlying critical performance indicators like cost, efficiency, and safety. Extraordinary effort has been made to engineer leak-tight systems capable of inducing and maintaining different vacuum regimes without significant loss of pressure due to leaks. Yet no system is perfect. Even the highest-quality chambers, gaskets, pumping ...

Fast neutron dose rate monitoring using off the shelf Helium-4 scintillation detectors
Abstract The capability to measure neutron dose rate with an accuracy of +/- 20% is demonstrated for the helium-4 fast neutron scintillation detector model s670 by Arktis Radiation Detectors. Measurements were performed utilizing quasi-monoenergetic neutron fluxes in an energy range between 0.144 and 14.8 MeV as well as using calibrated Cf-252 and Americium-Beryllium (Am-Be) sources. The elastic ...

Long-Term Volcano Surveillance via Volcanic Sediment Analysis
Why is Volcano Surveillance Necessary? Volcanoes pose a danger to life in many parts of the world. Eruptions occur relatively frequently, presenting risks to both health and infrastructure. The analysis of gas, liquid, and soil samples offers vital information regarding the levels of rare gas isotopes such as argon, neon and helium. Volcano monitoring requires the use of a number of methods to ...

WHY PEEK MATERIAL IS WIDELY USED IN SEALING TERMINAL & CONNECTOR APPLICATION IN OIL&GAS FIELD?
PEEK connector, we also call it PEEK sealing terminal or HTHP connector, just as its name implies which the connector is made from PEEK material combining with metal contact and using glass sintered technology sealing PEEk material & contact so it has perfect air leakage performance. In wellhead, gate valve requires to PEEK terminal for sealing, or tubing head spool for connect gauge or ...

Gas Chromatography and Breathe Safely While Using Nitrogen
Gas Chromatography and Breathe Safely While Using Nitrogen Gas chromatography is a process used to separate chemical compounds for analysis. The analytical chemistry process is used with gases that won't decompose when vaporized. Gas chromatography are used in a wide range of industries -- everything from forensic science to medical marijuana. While the procedure is highly useful, there are risks ...

Helium - What is the current cost to labs?
Talk of a helium crisis following the shortage of 2012/13 appears to have subsided thanks to increased worldwide production, with labs now readily able to obtain helium. Here we look at what has happened over the last 2 years since the global helium shortage was the hot topic in GC, where do we currently stand and what is the outlook in the short term? Helium Auctions A few weeks ago 275 ...

Cost-effective alternatives to helium for gas chromatography
Although there is now less concern about its availability, the price of helium is set to continue to increase meaning that cost-effective alternatives are still attractive to analytical labs. Many of the labs affected by the helium shortage of 2012-2013 have found that they are able to source helium readily although they have seen stark increases in price over the past 2 years. One direct ...

Helium and MRI Rooms Around the World
Helium gas is something most people feel fairly familiar with. Children are enthralled with the magical beauty of a floating balloon, watching it reach toward the sky and hoping not to lose their grip on the string. Helium feels safe, and while people surround themselves with flying wonders filled with this lightweight gas, the real magic of helium is taking place in MRI rooms across the ...
