Quality matters, because you need to focus on delivering accurate
results on the quality of the water sample, without worrying about
the quality of the consumables you use on a daily basis.
This is why GE Healthcare Life Sciences is committed to supporting
you with high-quality Whatman lters that are: Manufactured in ISO certied facilities
Reproducible, supporting consistent performance
Qualied for specic water monitoring applications(e.g., determination of suspended solids in water)
This brochure highlights the ltration solutions oered under theWhatman brand for the applications shown to the right.

Analysis of dissolved organic carbonsTypically, organic matter content can be measured as dissolved organic carbon (DOC), which is an importantcomponent of the carbon cycle. DOC is dened as the organic matter that is able to pass through a lter,typically one with a 0.45 m pore size.
Whatman Anotop IC lters are suitable for the preparation ofsamples for subsequent Ion Chromatography.
These lters contain a proprietary alumina-based AnoporeTMmembrane that exhibits very low levels of anion leaching(e.g., uoride, sulde, nitrate, nitrite) during IC testing.
