After placing the order, send us the components to be tested. These can be production samples or prototypes from the previous series. To ensure the quality of the analysis, the following points should be observed when taking samples as part of a residual dirt analysis:
- Hair protection: Wear a surgical cap
- Tools: Use tweezers or other clean tools
- Hand sampling: If necessary, always wear surgical gloves (without powder)
Packaging, storage and transport
Correct packaging and storage of samples is crucial to avoid falsification of results.
- Packaging:
- Pack individual parts in PE bags with a resealable closure
- Pack securely for transport to avoid damage
- Do not store multiple parts loosely in one bag (exception: bulk goods such as screws or small parts)
- Transport conditions:
- Protection against damage: Transport protected within the packaging
- Clean environment: Airtight and protected against moisture if necessary
- Low-vibration transport: To avoid abrasion and material changes
Note: Foreign contamination due to unclean working methods can falsify the measurement results and lead to costly wrong decisions.
Labeling of samples
Clear labeling is required to ensure your samples are correctly identified. The packaging should contain the following information:
- Customer name
- Part number
- Part name
- Date and location of collection
Samples that arrive at the laboratory and cannot be clearly identified or have been visibly contaminated during transport are automatically rejected. This is to avoid incorrect analyses and incorrect decisions.
Start of the analysis
- Initial sampling: During the first analysis of a component, a decline test is carried out to determine the analysis parameters. In addition to the actual test components, an additional part is required for the decline test.
- Follow-up analyses: The results of the initial sampling serve as a reference for all further analyses of the same component.
- Blank sample: Before each analysis, a blank sample is carried out to ensure the cleanliness of the filtration equipment.
We are at your side every step of the way to ensure that your analysis is carried out efficiently and precisely. If you have any further questions or need support during the commissioning process, please do not hesitate to contact us!
