Webinar: Advanced Approaches to Challenging Matrices

Webinar: Advanced Approaches to Challenging Matrices

Residue chemists often quantify compounds from a great variety of challenging matrices. Matrices may contain interfering components that can adversely influence the analysis. The challenge is to develop a method that is sufficiently selective to reduce/eliminate interferences and retain the analyte.

In this webinar, expert chemist Sidney Bluemink discusses techniques and instrumentation used to achieve a selective method for the analysis of challenging matrices. He covers investigations around extraction efficiency of non-labelled methods. Topics include ultra-cold processing, solvent extractions, dilution, traditional and dispersive solid phase extraction (SPE and dSPE), evaporation, deconjugation, matrix-matched calibration and using an isotopically labelled internal standard.
