Part 1: Basics of Ion Chromatography in Environmental Analysis


Since 1980s, Ion Chromatography has been widely used in environmental laboratories for the monitoring of anions, cations, oxyhalides, etc. These methods are under the jurisdiction of the Office of Water/Groundwater (ODW/OGW) and the Office of Solid Waste (OSW).

In recent years, under the Method Update Rule (MUR), ASTM methods have been adopted for regulations, monitoring, and permits. In this training course, attendees will learn about basic applicability of Ion Chromatography in environmental analysis.


  • Basic theory of Ion Chromatography
  • Anions and cations in drinking water, ground water, surface water, and waste water according to USEPA Method 300, parts A&B
  • Challenges with sample preservation and holding times
  • Myths and mysteries about the Minimum Detection Limit (MDL)
  • Quality control objectives according to applicable USEPA-adopted ASTM methods
  • Troubleshooting analytical issues for Ion Chromatography
