  1. Method 314.0 • Perchlorate by Ion Chromatography • Applicable to Drinking Water, Surface, Reagent and Ground water • Reporting limit: 4 ug/L is standard, 2 ug/L is achievable • Hold time 28 days • IC pump, sample injection valve, guard column, analytical column, suppressor device, conductivity detector • Eluent: 50% NaOH

  2. 314.0 Challenges • Particulate matter ( >.45 microns requires filtration) • High Conductivity ( High anion concentration) - MCT • No Second Column Confirmation - LFMS • Clients submitting non DW, GW samples for 314.0
