• Hi-Vol samplers are used for aerosols.
A range of size selective inlets (0.25 - 10 mm) can be used which separate out the aerosol particles on the basis of particle diameter.
• Cascade impactors separate the aerosol particles using the particles mass.
Most analytical equipment used in gas phase analysis is specific for one analyte.
• For Volatile Organic Compounds VOCs
Gas Chromatography (GC) is used to separate the array of organic compounds.
