In cooperation with the Leibniz Institute of Plant Genetics and Crop Plant Research, the company has released Customer Application Note 109: Primary Metabolite Analysis of Plant Material Using a Triple Quadrupole MS Coupled to a Monolith Anion-Exchange Column. This method combines separation using the 1 mm IonSwift™ MAX-100 anion-exchange column and ICS-3000 system and detection with the API 4000™ electrospray ionization (ESI) tandem mass spectrometry (MS/MS) system from AB SCIEX, providing a simple, rapid, specific, and sensitive method for the simultaneous detection and quantification of several primary metabolites involved in the tricarboxylic acid (TCA) cycle and glycolysis pathway. Compared to the previously used method, the IonSwift MAX-100 column facilitates shorter run times and helps achieve better sensitivity.

The biological pathways include many homologs and structural isomers with the same mass and analog fragmentations, so it is essential for the analysis to provide good resolution and specific identification of the different compounds.
