This SOP was requested by protocol reviewers and therefore, is being made available. A sample volume of 50 uL is introduced via a sample loop to the ion chromatograph where the anion of interest is chromatographically separated. The separated anion of interest is detected by a conductivity detector coupled with suppressed background. The analyte of interest is identified by their retention times and quantified by peak area.
Ammonium perchlorate is a strong oxidizer and potentially explosive.
This method is restricted to analysts experienced in the nuances of ion chromatography and in the interpretation of the resulting ion chromatograms or personnel under supervision of such an analyst. When analyzing unfamiliar samples, anion identification should be supported by the addition of spike solutions covering the analyte of interest. Ion chromatograph system is comprised of 2.1.1.1. Dionex autosampler, AI 350. Dionex conductivity detector, CDM-3.
