Optical particle counter (OPC) or microscopic evaluation?
The cleanliness of medical devices is crucial for patient safety and the effectiveness of the products. Various standards and guidelines, such as VDI 2083 Sheet 21, USP 788 and VDA 19.1 / ISO 16232:2018, provide information on the assessment of particle contamination. These describe methods for particle analysis that differ significantly in their application, objectives and informative value, but still represent the optimal approach for the respective purpose. It is therefore important to understand the differences between the methods and to use them correctly in order to achieve the greatest possible benefit.
