Cations in ultrapure water
Method to determine the cation content in ultrapure water samples using ion chromatography (IC). The analysis includes the determination of ammonium (NH4+), calcium (Ca2+), lithium (Li+), magnesium (Mg2+), potassium (K+), and sodium (Na+).
The sample must be collected in a container designed for ultrapure waters. Measurlabs can provide the required sample vessels.
