Hi all,
I would like to know your opinion about how to preserve TOC samples for cleaning validation:
- What is better: maintain the swab in the vial in WFI or dry until the assay? Why?
- I have read that it is recommended that if we are going to analyze the samples 24h after sampling, it is recommended to maintain them at 2-8ºC in an acid media. Is this correct?
Thank you very much in advance!
