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
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
