Chelex 100 is a chelating material from Bio-Rad used to purify other compounds via ion exchange. It is noteworthy for its ability to bind transition metal ions. It is a styrene-divinylbenzene co-polymer containing iminodiacetic acid groups. A concentrated solution of metals is obtained by eluting the resin with a small volume of 2 M nitric acid, which protonates the iminodiacetate groups. teams cqd templateWebApr 11, 2024 · (c) Chelex-100 suspension under the microscope.
