Detection in the Air

What are the available instrumentations to measure in the air?

To measure nanoparticles in the air, two types of instrumentation exist: the specific instruments which analyze some particles or the totality. Among those, it needs to be distinguished counters and granulometers, transportable (monitors, samplers) or portableThe counters provide a global number of particles and the granulometers specify the size distribution. A global count of the particles will be less precise and will not permit the detection of small leaks. Measures may perform in real or deferred time.
