Method 314.0

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