Airborne Particles

The size and/or attention of airborne elements can be measured straight using Microns to Measure's

Specialised equipment - though not by us.

Microns to Measure easier approach is to draw air through a filter, trapping the particles. The attention of particles can be determined by weighing the filter after an appropriate period of sampling.

If we can recover the particles from the filter, then we can also find particle size.

It is essential to use a filter medium that will release the particles cleanly. We have had good outcomes from PTFE filters (eg. Millipore) and Whatman 541 (hardened paper). Glass fibre filters are not appropriate, because they split up and pollute the sample.
