General description

In order to assess any variations in LC-MS-based metabolomics analysis data, it is recommended to add an additional QC (quality control) sample at the beginning of every analytical experiment batch. It is recommended that QC be injected every 4-10 injections into the workflow steps. The QC sample evaluates any drifting phenomenon like intensity values, ion suppression, or any changes in the retention time of the material’s peaks in the LC-MS data. The Polar Metabolites QC Mix is a ready to use solution for mass spectroscopy workflows. By utilizing the QC mix, the user will be able to assess drifting and ion suppression phenomenon. The Polar Metabolites QC Mix is comprised of 8 components (Uridine, Adenosine, Nicotinic acid, Biotin, Phenylacetylglutamine, L-phenylalanine, Cytidine and L-Tryptophan) which covers ~ 100-500 Da mass range.

Features and Benefits

  • The mix was designed for ESI (+/-) detection.
  • The mixture comes as a ready to use solution(~9:1 ACN:10mM ammonium formate, inwater) format in crimp top (Silicone/PTFE liner) amber vial, which is suitable for use with most of the LC-MS autosamplers.
  • The recommended storage temperature of the mixture is 2-8 °C, thawing of the sample is not required.
