An archaic idea of microbial retentive filtration would lead one to equate a filter's rating With all the Wrong effect of a straightforward sieve or display screen that Unquestionably retains particles sized at or higher than the filter's rating.
CHEMICAL CONSIDERATIONS The chemical attributes of Purified Drinking water and H2o for Injection ended up specified by a series of chemistry tests for different distinct and nonspecific attributes With all the intent of detecting chemical species indicative of incomplete or inadequate purification.
