Spraying
Sampling by free stream:
Spraying is the local application of fluid on the part with a spurt. The method is suitable for cleaning exterior geometries and accessible internal geometries.
The spray method allows – depending on the geometry of the respective control areas – to apply different parameters to achieve the most efficient release of particles.
Here are the particles collected on a membrane and analyzed.
The characteristic parameters such as flow rate, nozzle geometry, spray distance, amount of liquid and spray pressure are determined by the Decay curve
