How to choose the appropriate
dust sampler
Vrins Luchtonderzoek has several dust samplers available, for rent and
for sale. A short description of the samplers is given on this website.
In the table below, the most important features of the samplers are shown.
The most important feature is the particle size fraction that is sampled.
Other features are typical time resolution, on-line or off-line, size
resolution (optical or aerodynamic) and typical stand-alone time for long-term
measuring campaigns.
