[Analysis Case] Evaluation of Residual Contaminants in Blood Components

Visualization of wipe residues using TOF-SIMS

When describing cleaning methods in brochures for medical devices, it is necessary to confirm the validity of those cleaning methods. In this case, as a verification experiment for the wiping method of medical devices, we applied bovine serum albumin (BSA), a blood model drug, to sheets of acetyl cellulose (TAC), SUS-made scalpels, and glass, and evaluated the residual components before and after wiping using TOF-SIMS. As a result, it was found that ethanol is more suitable than water for wiping BSA, and that the wiping effectiveness varies depending on the substrate. Measurement method: TOF-SIMS Product field: Medical devices and pharmaceuticals Analysis purpose: Composition evaluation, identification, composition distribution evaluation, failure analysis, defect analysis For more details, please download the materials or contact us.
