| IonPac TAC-2 Trace Anion Concentrator | 043101 |
| IonPac TAC-2 Trace Anion Concentrator, Pkg of 4 | 043102 |
The IonPac? TAC-2 Trace Anion Concentrator Column is a pellicular anion-exchange concentrator column with moderately low void volume (~50 μL). The TAC-2 is designed primarily for high-purity water analysis. The TAC-2 strips ions from a measured volume of aqueous sample matrix, concentrating the analyte species and lowering detection limits.
Can be used with carbonate/bicarbonate and borate eluents
Note: Not solvent compatible.
