1. What is 21 CFR part ?
Title 21 CFR Part of the Code of Federal Regulations deals with the Food and Drug Administration (FDA)
2. Different between Qualification and Validation?
“Qualification” refers to the activities performed on facility, utility and equipment
The “Validation” refers to the activities performed on processes, practices and methods.
3. Critical utilities in Injectable facility
Air Handling System
Pure steam Generation and Distribution System
Purified Water Generation and Distribution System
Water for injection Generation and Distribution system
Compressed air
Nitrogen
4.What is dead leg?
A dead leg is defined as an area in a piping system where liquid can become stagnant and not be exchanged during flushing.
5. Difference between SS316 and SS316L
6. What is the recommended bio burden limits of purified water & WFI?
Purified water has a recommended bioburden limit of 100 CFU/mL,
Water for injection (WFI) has a recommended bio burden limit of 10 CFU/100 mL.
7.How many Phases of water system Qualification?
Qualification of pharmaceutical water system involves three phases
Phase -1
Phase -2
Phase -3
8. What needs to be checked during AHU validation?
During AHU validation, following tests shall be carried out
Filter efficiency test,
Air velocity & number of air changes,
Air flow pattern (visualization)
Differential pressure, temperature and RH

I definitely enjoying every little bit of it and I have you bookmarked to check out new stuff you post."
ReplyDeleteReally the blogging is spreading its wings rapidly. Your write up is a fine example of it.
Pharmaceutical Sciences MSC OSPAP in Sunderland university UK
Maks: I like your website
ReplyDeleteBeing a medical related person, I really wonder the benefits of this site to deal more about pharmaceutical water purification systems for candidates of QC, QA and F R n D.
