Dionex IonPac ICE AS6 Column Performance Test Using its QAR Method

Instrument Type: IC

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>

Fast and reliable method for the analysis of methylmalonic acid from human plasma

Instrument Type: LCMSMS

To describe an accurate and precise high-throughput analytical technique for the analysis of methylmalonic acid (MMA) utilizing Thermo Scientific SOLAµ WAX followed by LC-MS/MS. This technique further separates MMA from the known endogenous interference succinic acid (SA), a compound that has the same molecular weight as MMA and demonstrates a similar fragmentation pattern, which can cause issues with selectivity in mass spectrometry (MS) detection. For Research Use Only. Not for use in diagnostic procedures.

AN71410: Ion Chromatography: A Versatile Technique for the Analysis of Beer (Part D: Organic Acid Analysis)

Instrument Type: IC

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.

Fast analysis of organic acids in white wine on a Thermo Scientific Acclaim Organic Acid (OA) column

Instrument Type: HPLC

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.
