IonPac AS19 阴离子交换色谱柱
  The IonPac AS19 i是一款高容量，氢氧根体系阴离子交换色谱柱，
    For determination of oxyhalides and inorganicanions

  The IonPac AS19 hydroxide-selective anion-exchange column is specifically designed for trace bromate in drinking water. Its high capacity and selectivity allow the determination of bromate in drinking water at the low-μg/L level. The AS19 meets the performance requirements of US EPA Methods 300.0 and 300.1.
• Recommended hydroxide-selective column for trace bromate in drinking water matrices
• High capacity: 240 μeq per column （4 × 250 mm）
• Meets or exceeds performance requirements of US EPA Methods 300.0 and 300.1
• Column selectivity is optimized for a 30 °C operating temperature
• Compatible with organic solvents
• Low backgrounds and enhanced analyte sensitivity with the ASRS 300 and an RFIC system
  The AS19 is designed for the analysis of oxyhalides and common inorganic anions including fluoride, chlorite, bromate,chloride, nitrite, bromide, chlorate, nitrate, phosphate, and sulfate in drinking water, groundwater, wastewater, and other diverse sample matrices. The AS19 allows analysis of most drinking water without the use of sample pretreatment or preconcentration. The AS19 column is ideally used with an RFIC system for automatic eluent generation.
  The key application for the AS19 is the determination of trace bromate in drinking water matrices using a potassium hydroxide gradient with suppressed conductivity detection. The selectivity of the AS19 ensures that bromate, a toxic byproduct of ozone disinfection, can be quantified at low μg/L concentrations using suppressed conductivity detection even in the presence of very high concentrations of chloride, sulfate, and carbonate.
Note: Use the Anion Self-Regenerating Suppressor （ASRS 300） with the AS19 column for eluent suppression.
