Hi All,
I am due to host a Webinar called "Do You Know What's in Your Laboratory Water?" I know very little about the techniques used to purify water for laboratory use. If anyone could point me in the direction of some good websites that will help me prepare for this Webinar it would be much appreciated. The Webinar is coming up very soon (see below):
