Collection substrates

Collection substrates

Different types of collection substrates can be used on the DGI impactor collection plates. The collection plates used in the DGI are designed for 47 mm substrates and Dekati offers aluminium substrates for this purpose. For the suitability of different types of substrates, please contact support@dekati.fi.

The collection substrates can be greased to prevent bounce and blow-off of the particles. The particles stick better to the greased surface, and the effect of bounce can be greatly reduced or completely prevented. Dekati provides suitable grease for this purpose in two different forms: grease that needs to be dissolved in a suitable solvent and then applied on the substrates, and grease already dissolved in the solvent and provided in a form of spray. More information on the Dekati® Collection Substrate Spray can be found here.
