The Working Principle of Multistage Roots Vacuum Pumps

Fore vacuum pumps are defined as those which exhaust to atmospheric pressure. They are also required to support secondary pumps or to attain the initial conditions for their operation. There are two types of fore vacuum pumps:

When to Use Direct vs Indirect Gauges

 

Measuring vacuum pressure is a fundamental element of all vacuum applications, but there’s no such thing as a universal vacuum gauge.

When it comes to measuring vacuum pressure, no single gauge will respond accurately throughout the entire vacuum range (from atmospheric pressure to 10-12 mbar). That’s why a clear understanding of the differences between the types of gauges is essential to match them to the right operational contexts.

5 Ways Vacuum Contributes to Space Simulation & Research

 

Space technology and research would be nowhere without vacuum technology. But, with such complex work, it’s easy to lose sight of where (and how and why) vacuum plays such an important role. So we’ve published a new eBook that unpacks the most common applications of vacuum technology in space — with details on how it supports space flights, space simulation and vacuum testing and fundamental space research.

Mass Spectrometry in Forensic Science – a brief history

What is mass spectrometry?

Mass spectrometry – an analytical technique that measures the mass-to-charge ratio of ions and, in forensic science, one of the best ways for toxicologists to identify and analyse substances.

In the forensic community, it’s heralded as the “gold standard” and the “near universal test” for isolating and assessing unknown agents. As a result, its widest application is in the analysis of drugs (including drug metabolites and drug paraphernalia).

ASMS 2020 Reboot: The development of Mass Spectrometry

The American Society for Mass Spectrometry (ASMS) is the largest society in the world of Mass Spectrometry and its applications. Its Annual Conference is held at varying locations in the USA and Canada with around 6,500 participants, some 3,000 posters and 400 oral presentations alongside a large vendor exhibition. This year's conference was planned in Houston, Texas for May 31 - June 4 but was cancelled due to the COVID-19 pandemic. As a result, the conference was shifted from a face-to-face event into an online format.

How has COVID-19 affected the US vacuum technology industry?

For business and organisations in the vacuum technology space, COVID-19 has changed the way in which they operate indefinitely – with many experiencing the effects in different ways. It has, without a doubt, been a harsh and challenging year, but signs of recovery are on the horizon as government-imposed lockdowns ease and many of these businesses and organisations resume (in some way) operations. .

Dry vacuum pumps in the food industry

In December 19, 2019 we mentioned that dry screw pumps in food industry application are more often replacing wet pumps. We found a useful link about dry vacuum pumps in food packaging. Please follow https://blog.leybold.com/disrupting-food-packaging. In this blog, Jim Hupp, an experienced technician working in the Midwest USA explains the advantage of dry pumps compared to other pump types in this industry.
