Analysis of Environmental Waters for Cations and Ammonium Using a Compact Ion Chromatography System

using 4-µm-particle columns. MATERIALS AND METHODS Sample Preparation Samples were filtered using 0.2 µm syringe filters prior to analysis. Aqueous soil extracts were prepared by adding 30 mL of 30 mM methanesulfonic acid (MSA) to 3.0 g soil and sonicating…
