My Chelex 100 (Product C7901) in my column dried out. Can I still use it?
The resin may be rehydrated and used, as long as it remains white. If the color of the re-swollen resin is yellow, do not use it.
I want to use Product C7901, Chelex 100, to make a metal-free solution. However, the water wash from the Chelex resin is very basic. How can I fix this?
A suspension of Chelex 100 (sodium form) in water typically has a pH of 10-11. This pH can be slowly lowered by extended water washing, or by using a buffer. The sodium form at pH 6.3 can be obtained by rinsing with at least 4 bed volumes of 0.5 N sodium acetate buffer, followed by 5 bed volumes of water. This is a more common method for making metal-free distilled water.
What is the particle size of the resin in Product C7901, Chelex 100?
The particle size for this resin is 45-165 microns. The mean particle size is 90 microns.
