TL;DRAbstract

This slide presentation reviews the testing for Non-Volatile Residue contamination transferred to surfaces from handling and solvent cleaning. Included in the presentation is a list of the items tested, formal work instructions dealing with NVR. There is an explanation of the Gravimetric determination method used to test the NVR in a variety of items, i.e., Gloves, Swabs, Garments, Bagging material, film and Wipes. Another method to test for contamination from NVR is the contact transfer method. The use of this method for testing gloves, garments, bagging material and film is explained. Certain equations use in NVR analysis and the use of a database for testing of NVR in consumables are reviewed.
