Hi everyone!
I have an unknown material on a tablet press that I would like to swab in cleaning validation studies. However, since I don’t know what it is (the company -Manesty- does not exist anymore and I is impossible to get a material certificate), I can’t do recovery study on this material.
Currently, we only assess this part visually. But I need more than that. What are my options?
- Execute the recovery test on the piece itself : difficult since the equipment is used often.
- Is is possible to test the material by any mean to find what it is? Maybe a company can do this test?
- I can’t replace this part by a new one.
Please can anyone tell me what is acceptable in this condition.
Thank you in advance for any of your help!
