Control measurements of nanoparticles

Since nanoparticles are invisible to the eye, it is only possible to do a control measurement in order to evaluate if an exposure to airborne nanoparticles occurs.

When handling nanoparticles, the level of nanoparticles must be measured, similar to the poison alarms when working with toxic gases.

Typically, control measurements are needed when initiating new processes, to check that the equipment and work procedure do not release nanoparticles outside the closed system. It is quickly determined whether the conditions are sufficient to keep the particles inside the closed systems. In this way, everyone is assured that the procedure for handling is safe.

The control measurements are also effective to monitor a process or to release a room after cleaning.

The nano-responsible at the Institute is expected to be trained to conduct the control measurements.

It may be difficult to know where to position the control device in relation to what you want to measure. In the nanoparticle networking group, we regularly exchange experiences, and they will be updated here.

Unfortunately, the control measuring devices costs a lot. At DTU we have best experience with NanoTracer and DiSCmini:

There are probably other suitable control measuring devices.
