This Application Note expands the scope of the EPA Method 314.0 to the 2-mm column format. It evaluates and describes the linear range and initial demonstration of capability. Initial demonstration of capability includes determination of method accuracy, precision, detection limit (MDL), and matrix conductivity threshold (MCT). This document also describes perchlorate recovery in field samples. Overall, the results presented here meet or exceed the performance requirements specified in U.S. EPA Method 314.0. (This part has an one-click workflow for ICS5000 and AS-DV Autosampler).

This Application Update updates the EPA Method 314.0 for perchlorate determination in drinking water with an improved suppressor, the Dionex™ AERS 500 suppressor. The Dionex AERS 500 suppressor is a superior suppressor as it provides high capacity, low noise, high backpressure resilience, and fast startup. Moreover, the AERS 500 suppressor minimizes peak dispersion and improves peak efficiency. This document evaluates and describes the linear range and initial demonstration of capability (EPA Method 314.0, Section 9.2). (This part has a one-click workflow using ICS5000 and AS-DV autosampler).

This application update describes the determination of perchlorate using the procedure outlined in EPA Method 314.0. This application used an integrated ion chromatography system with a 4 mm Dionex IonPac AS16 column, a Thermo Scientific™ Dionex™ EluGen™ EGC II KOH cartridge, a 1000 µL injection, and suppressed conductivity detection with a Dionex ASRS ULTRA II operated in external water mode.
