Sometimes deposits and residues are found on damaged parts, filters or near oil- or grease-bearing pipes. The analysis is intended to provide information about their formation. You can remove the residues that are of interest to you, e.g. with suitable aids and fill them in a plastic bag or a container.
In the case of multi-layered filter media, a portion of the filter fabric is sufficient. Always take a representative sample and avoid the sending of the entire component, as otherwise additional costs for sample preparation and disposal will incur.
You should preferably download a Sample Information Form and indicate that the reason for analysis is a "residue analysis".
Or order an analysis kit 5. This contains a sample bottle for sending back the filter fabric, a Sample Information Form and an envelope.
Normally an analysis and comparison of the residue with possible source-media provides the most meaningful results.
Our technical team will be happy to advise you on the best way to send us your samples.
