AN146: Determination of Trace Anions in High-Purity Waters by Ion Chromatography Using High Volume Direct Injection.
Description
This application note describes an ion chromatographic method using the microbore IonPac AS17 column to determine trace concentrations of common inorganic anions, low-molecular-weight organic acids, as well as acrylate, methacrylate, benzoate, and phthalate. These contaminants can come from some of the following sources: cleaning agents, adhesives, oils, and solder fluxes. Anionic contamination is known to cause corrosion in microelectronic circuitry. The analytes are detected by suppressed conductivity with a 2-mm ASRS ULTRA operated in the “Gas-Assisted Recycle” mode.| Market: | Environmental |
