AN247 (a): Determination of Morpholine, Ethanolamine, and Hydrazine in Simulated Nuclear Power Plant Wastewater

Instrument Type: IC

This Application Note describes the determination of μg/L concentrations of hydrazine, morpholine, and ethanolamine (ETA) in a simulated NPP wastewater sample containing mg/L concentrations of common cations. Morpholine and hydrazine are separated using an IonPac CS16 column with electrolytically generated methanesulfonic acid eluent. See AN 247 (b) for ETA separation on an IonPac CS15 column.

AU137: Determination of Trace Lithium in Industrial Process Waters

Instrument Type: IC

In a variety of situations, carryover from one body of water to another is measured by monitoring a tracer compound. Lithium is a good choice for a tracer because it is very soluble and has a low background concentration in public water supplies. This Application Update describes a rapid and sensitive ion chromatographic method for the determination of trace lithium using a microbore IonPac CS12A column.
