Application Note: Removal of Endotoxin, RNase, DNase and Bacteria using the PURELAB Option-Q fitted with a Biofilter
20 May 2008

The Biofilter, when fitted to the Option-Q, is very effective for producing water which is free from biologically active impurities. This makes it suitable for use with applications which require endotoxin free ultra-pure water, bacteria free water, and nuclease free ultra-pure water.

This technology note explains several experimental challenges to determine endotoxin, DNase and RNase, TOC and resistivity, and bacteria levels in ultra-pure water from the Option-Q.
