 Interview with Dr Andrew Chew

By Vacuum Science World News

In another addition to our expert interview series, we spoke to Dr Andrew Chew, who is a Global Applications Manager in the Scientific Vacuum Sector. In his role, he is developing customised solutions for a large number of R&D applications such as Surface Analysis, Electron Microscopy, Mass Spectrometry, and many more. Find out more about his background and involvement with vacuum technology by reading our Q&A below.

Working with turbomolecular vacuum pumps

By Peter Lambertz

Working principle Turbomolecular pumps (TMPs) are kinetic vacuum pumps which operate using a very fast spinning rotor (usually rotating at between 24,000 and 90,000 RPM). Their typical operating pressures are in the high to ultra-high pressure range between 10-3 and 10-11 mbar, employing pumping speeds of between 10 and 4,000 l/s.

How to find the right vacuum pump system for your lab work

By Andrew Chew

Laboratory technicians and scientists regularly use vacuum pumps (frequently of the bench-top variety) for a range of tasks including aspirating/filtering, controlling or inducing solvent evaporation in concentrators, as well as in gel driers, vacuum ovens, desiccators and rotary evaporators.

Eight top tips for working with oil-sealed rotary vane pumps

By Andrew Chew

Rotary vane pumps are considered wet, positive displacement pumps, with the term “wet” denoting that the gases being pumped are exposed to oil. The significant characteristic of oil sealed rotary vane (OSRV) pumps is the use of oil as a sealant, which is not found in ‘dry’ pumps.

Four ways of finding vacuum leaks using helium

By Peter Lambertz

Wherever and whenever a vacuum needs to be created, it is essential to ensure its integrity (i.e. the “tightness” of the system). If the system is not tight, then time is squandered and effort is pointlessly spent trying to create a vacuum in an “open system” which could never support a vacuum in the first place.

Introduction to the fundamentals of vacuum science & technology

By Peter Lambertz

Described as ‘a space in which the pressure is below surrounding atmospheric pressure’, vacuum science is a subject and concept that has stimulated many great minds for millennia. The origins of vacuum science can be traced back to as early as the 4th century when Aristotle stated that ‘nature abhors a vacuum’.

ITER: Clean and sustainable energy (using vacuum vessels)

By Andrew Chew

Energy from nuclear fusion must surely be the answer to the majority of the world’s on-going energy headaches. The fuels used in nuclear fusion are plentiful and readily available across the world. There are absolutely no greenhouse gas emissions and - unlike even the most up-to-date nuclear energy programmes - not only are there no long-term radioactive wastes to deal with, but the reactors cannot “run out of control”.

The main CERN vacuum systems explained

By Andrew Chew

The study of particle physics is conducted in machines known as particle accelerators (or particle colliders). These machines use huge electromagnetic fields to accelerate proton particles to velocities approaching the speed of light, focus them into a fine beam, and then monitor the matter that results from their collision with other particles.
