Preparation method will depend upon the type of part or component and the sample size to be analyzed. Determine the solution required for the specific part and sample size.
Extract contaminant particles from parts and components with spraying, rinsing, or ultrasonication. The cleaning solution is then passed through a filter, the type depending on the parts cleaned, and the particles retained on membranes for analysis. Washing cabinets and filters of different sizes from PALL are used for this task. Filters are dried and then evaluated.
The particles are detected, quantified, and classified according to their size and type, i.e., their potential to cause damage. It is done with a Leica Cleanliness Analysis Solution using a compound or digital microscope and Cleanliness software module.
Review results from the analysis and identify if any potentially catastrophic particles are present. Metal particles have a higher potential for damage and the Leica imaging solution can identify metallic particles automatically. These potentially catastrophic particles can influence the longevity of a component or even cause a system failure.
With the results from a full cleanliness analysis, step by step the workflow can be optimized. Then the potentially catastrophic particles can be identified and the source of contamination determined and eliminated. The aim is to always improve the cleanliness analysis process in order to eliminate and minimize contamination.
