Iontosorb IDA
Chelating sorbent
With iminodiacetic acid bound covalently in side chains of bead-form cellulose:
 |
The sorbent has applications not only as a chelating sorbent, but it is especially proper for Metal Ion Affinity Chromatography (IMAC).
Technical Parameters
Iontosorb IDA (non-magnetic sorbents) or Iontosorb MG IDA (magnetic sorbents) is delivered with the following content of functional groups:
| Content of functional groups mmol Cu / gram dry sorbents | |
|---|---|
| LOW | 0.06 - 0.10 |
| MEDIUM | 0.11 - 0.15 |
| HIGH | 0.16 - 0.20 |
| VERY HIGH | 0,21 - 0,29 |
In an order a demanded content of functional groups shall be given (e.g. Iontosorb IDA 100 M means demanded content of functional groups 0.11 - 0.15 mmol/g dry; Iontosorb MG IDA 100 L means demanded content of functional groups 0.06 - 0.10 mmol/g dry).
