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. .

Diaphragm Vacuum Pumps - how they work and where to use them

.Functional Principle 

Diaphragm pumps - also known as membrane pumps - are positive displacements pumps used in the rough vacuum range from 0,5 to 1000 mbar. A membrane (rubber, Viton ® or Teflon® ) is moving up and down in the pump body compressing and exhausting gas coming from the inlet. Inlet and exhaust check valves are actuated by the pressure difference.

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.
