Before 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>

Citric acid is a common ingredient found in pharmaceutical formulations. An assay for citrate and phosphate in pharmaceutical formulations using ion chromatography with a Thermo Scientific Dionex IonPac AS11 hydroxide-selective, anion-exchange column and suppressed conductivity detection was validated in Application Note 164. The method incorporates an electrolytic eluent generator to automatically produce an isocratic potassium hydroxide eluent. This record shows that the method can be run using the Thermo Scientific Dionex Integrion system.

This 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.

The Thermo Scientific HPLC system is applied for the analysis of organic acids in white wine. The separation is performed on a Thermo Scientific Acclaim Organic Acid (OA) column, with UV detection at 210 nm. The samples were prepared using Thermo Scientific Dionex OnGuard II P SPE cartridges.

The Thermo Scientific HPLC system is applied for the analysis of organic acids in orange juice. The separation is performed on a Thermo Scientific Acclaim Organic Acid (OA) column, with UV detection at 210 nm. The samples were prepared using Thermo Scientific Dionex OnGuard II P SPE cartridges.
