Dionex IonPac ICE AS6 Column Performance Test Using its QAR Method
Instrument Type: ICBefore running any samples, Thermo Scientific recommends that you first confirm the performance of the column by reproducing the lot validation report chromatogram shipped with column.Compare your results with the one reported in the quality assurance report. At least three injections should be made. This record provides an eWorkflow for executing the QAR method on an ICS-5000 system.<enter final 90 characters of description>
TN46: Determination of Trace Anions in Concentrated Glycolic Acid
Instrument Type: ICThis Technical Note describes the theory, set up, and analytical procedure for the determination of trace chloride and sulfate at sub-mg/L (ppm) levels in 0.7-17.5% (v/v) glycolic acid.
TN44: The Determination of Trace Anions in Concentrated Phosphoric Acid
Instrument Type: ICThe determination of trace anions in phosphoric acid is hampered by a large excess of phosphate ion. Diluting the concentrated sample overcomes the problem of a large concentration of the interfering matrix ion, but lacks the required sensitivity for the contaminant ions of interest. An improved method for determining trace anions in concentrated phosphoric acid has been developed to overcome this problem. This Technical Note describes the theory, set up, and analytical procedure for the determination of chloride, nitrate, and sulfate at sub-mg/L (ppm) levels in 85% (w/w) phosphoric acid.
AN71410: Ion Chromatography: A Versatile Technique for the Analysis of Beer (Part D: Organic Acid Analysis)
Instrument Type: ICThis application note describes the use of ion-exchange or ion-exclusion chromatography for the determination of five classes of compounds of interest to the brewing industry, including: carbohydrates, alcohols, organic acids, inorganic anions, and inorganic cations. One of two forms of electrochemical detection is used, pulsed amperometry or conductivity detection. This part of the application note describes organic acid analysis which uses conductivity detection. This was formerly Dionex AN46.
