面议The IonPac® AS9-SC is designed for the isocratic separation of oxyhalides and inorganic anions, including fluoride, chlorite, bromate, chloride, nitrite, bromide, chlorate, nitrate, phosphate, and sulfate in drinking water, wastewater, groundwater, and other diverse sample matrices.
For fast analysis of oxyhalides and inorganic anions at similar concentrations
Ideal for simple sample matrices
Common inorganic anions and oxyhalides can be determined in less than 10 minutes using an isocratic carbonate/bicarbonate eluent coupled with suppressed conductivity detection.
The IonPac AS9-SC column is specified in US EPA Method 300.0 (B), and meets or exceeds the performance requirements of this method. Use the Anion Self-Regenerating Suppressor (ASRS® 300) with the IonPac AS9-SC column.
Note: See also the IonPac AS23, the recommended column for the analysis of oxyhalides, including bromate.
