TN48 (Method 2): Determination of Trace Anions in High-Purity Water by High-Volume Direct Injection with Online Eluent Generation
Description
This note describes the use of the eluent generator with the high-volume direct-injection technique to determine trace anions in high-purity waters. The ability to generate high-purity and carbonate-free eluents on-line improves performance for trace-level analysis. Retention time reproducibility is improved, especially for early-eluting species. The baseline shift from the hydroxide gradient is significantly reduced. Two columns are described: the 2-mm IonPac AS11 & 2-mm AS15. Common inorganic anions and low molecular weight organic acids are determined below μg/L levels in less than 35 min.| Market: | Water Analysis |
