At present, IPA water demonstrates very limited cleaning performance, which in turn confirms that any analytical extraction method using this solvent mix cannot and will not provide an absolute cleanliness assessment, just a relative one.

Further, Milton and co-authors and Thorne and co-authors have suggested that endotoxin binds with varying degrees to different filter materials, enhancing the variability in endotoxin recovery during analytical extraction (Milton, Gere, Feldman, & Greaves, 1990; Thorne et al., 1997).
