nonsenses & truths

We've been asked at work to review our helium requirements, and propose options for using it more efficiently.  Helium is a finite resource, used amongst other things to cool the magnets in MRI scanners.  So perhaps we should stop filling balloons with it.

In my lab we use it for measuring the density, surface area and porosity of powders - these could be catalysts (in car exhausts), biofuels, or pharmaceuticals.
