100 Years of the Holweck Vacuum Pump

 

2020 marks the centenary of the development of the Holweck pump by the French physicist Fernand Holweck. As well as a stand-alone pump the Holweck design is used as a compound pumping stage in the widely employed TURBOVAC, nEXT and STP pumps. In this respect the Holweck design has been utilised to make significant advancements and improvements to the development of turbomolecular pumps over the last half century.

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).

How to fix a vacuum system leak – things to consider

 

As applications using vacuum technologies evolve and become ever more precise, the vacuum systems and pumps used have even less margin for error than ever before. In every operation that uses vacuum – particularly where incredibly precise instruments are involved (R&D, mass spectrometry) – the preservation of the vacuum is of the utmost importance.

The reality is that unforeseen problems in a vacuum can be catastrophic for the process, the environment and the operator, and one which can prove tricky is a vacuum leak.

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. .
