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>

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 glycolic and related acids. The separation is performed on a Thermo Scientific Acclaim Organic Acid (OA) column, with UV detection at 210 nm.

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 Acclaim Mixed-Mode WAX-1 and Organic Acid columns are compared for the analysis of organic acids, with UV detection at 210nm. The unique chemistry of the Acclaim Mixed-Mode WAX-1 column cleanly separates compound which are challenging to separate using reversed-phase columns.
