Quality control of membrane filters with model strains: analyticalscope oforiginaldata
Official protocol of quality control of membrane filters described in MU 2.1.4.1057-01 is outdated and requires updating. The using of Student's test allows to get more objective evaluation of membrane filters quality. The optimal solution of methodical problems of MF's control is the use of two-component system consisting of a strain of E. coli M1702 and other, for example, E. coli 675, which has worked well in comparative tests and is permitted for use in routine water laboratories.
