SoloHill Particle Validation Standards

As international demand for pharmaceutical product quality increases, so does the need for reliable, efficient control of particulate contamination. The unintentional presence of extraneous, mobile and undissolved particles in a parenteral solution must be detected and remediated as part of any robust quality program. Pharmaceutical processes can include several sources of potential particulate contamination: shards from chipped glassware, fibers from cleanroom cloths, stainless steel shavings from the production area, and many more. Detection of these contaminants through manual or automated methods is necessary to ensure affected units never reach the clinic. SoloHill Particle Validation Standards support the training and testing of human inspectors and are designed to challenge and validate both manual and automated visual inspection methods.
