For this section, the term swab or swabbing is used; however, descriptions for swab recovery studies also apply to wipe sampling, except as noted. For swab recovery studies, coupons are spiked in a controlled manner with solutions of the sampled residue, allowed to dry, and sampled with the swabbing procedure to be utilized in the cleaning validation protocol.Rinse recovery studies, like swab recovery studies, can be performed on coupons that have been spiked with solutions of the target residue and then allowed to dry.
在多处出现这个“allowed to dry”的说法,我也怀疑这个必须干燥的前提不是一个必要的条件,而是一个惯常的做法!@hongwei2000 @windy @谢大侠来了
