Water Testing in High Purity Water Systems… How is it tested?

Posted by:

You use water for your experiments every day, but how much confidence do you have in its purity? Fortunately, you don’t have to check that it satisfies your needs each time you use it, as there are systems in place in most laboratories to make sure it is what it says on the tin. However, it’s still good to know how those tests are conducted, so that you can troubleshoot your experimental problems if you’re suspicious of your water. Regardless, ...

When it comes to medicinal drugs, it is essential that no chemical species is introduced which could possibly interact with and impact on the safety, quality and efficacy of the drug. Extractables and leachables both migrate from the packaging into the drug however, migration for extractables is facilitated by a solvent, while leachables migrate with direct contact at room temperature. In ...

Dealkalization Process- An overlooked method in High Purity Water Systems

Posted by:

Dealkalization is the process of removing anions such as bicarbonates, carbonates,
sulfates, and nitrates with a chloride anion exchange. This process treats softened water
with a chloride form anion resin that exchanges chloride ions for anions in the feed water.
Dealkalizers use a Type 2 strong base anion resin such as ResinTech SBG2. The resin is
regenerated by salt (typically at a dosage rate of 5 lbs/cf), and removes up to 95% of
carbonate (CO3) and bicarbonate (HCO3) alkalinity as ...
