We have a chemical lab. We are doing chemical analysis using gas chromatography (GC). İn order to confirm that we properly operate standard method we did some studies called method verification.That is repeatability , LOD;LOQ; Recovery ,?studies.
Now we are planning to move another location where it?s laboratory facilities better than existing one . After moving all balances will be calibrated and GC will be subjected to performance and operational calification ( PO and OQ) test by vendor again.
My question is after moving new lab. all verification studies (repeatability , LOD;LOQ; Recovery etc..) should be done from beginning to end again? Or to what degree these studies should be done?
Thanks again

Tacom, sorry to ask another question.

But does your organization have established Change Control? Hopefully you have some language already established for this type of move.
To answer your question, I would say it would depend on how the initial validation was conducted and the IQ of the equipment/instrumentation. For example, if you are moving an analytical balance, I would suggest that all the measurements should be repeated, as there are so many variables related to the environment that could affect those.
However, I would probably guess that the GC is less prone to IQ factors as the analytical balance. However, you have to disconnect hoses/lines, and individually move all those components. When you move it all back in the new place, hopefully you can have the vendor perform some type of maintenance/re-qualification on it. I would perform a system suitability on it to assure everything is OK. Within that suitability, you could verify repeatibility and such.
IMO, the level of activity required after the move depends on the accreditation body (as mentioned), existing Change Control documentation, Risk, and how well/thorough the original IOQ was performed. Saying, it may have a chart or something in it to demonstrate what actions are needed for a particular change.
