- Scope
- This standard specifies a method for the determination of potassium, sodium, lithium and ammonium by ion chromatography. This standard is applicable to the determination of potassium, sodium, lithium and ammonium in groundwater. When sampling 100uL, the minimum detection concentration (mg/L) is potassium 0.05, sodium 0.05, lithium 0.005, and ammonium 0.05. The detection limit (mg/L) is potassium 2.0, sodium 10.0, lithium 0.1, and ammonium 1.0.
