Analysis of Amitraz (sum) in samples with incurred residues - Comparison of the approach covering the individual metabolites via LC-MS/MS with the approach involving cleavage to DMA. Julia Hepperle, Irina Sigalov, Dorothea Mack, Sigrid Sch ler, Michelangelo Anastassiades E-Mail: Introduction LC-MS/MS Analysis Amitraz m/z 294/122. The current MRL residue definition (RD) for amitraz Column: Phenomenex Synergi Hydro RP ( m, x 100 mm) Guard-column: Phenomenex AQ C18 (4 x mm). ( Sum of amitraz plus all its metabolites containing the Intensity, cps Mobile Phase: 2,4-dimethylanilin moiety ) requires methods that A: 5 mmol NH4-Formate in water + 5% methanol involve hydrolysis to 2,4-dimethylanilin (DMA).
In 2007 the EURL-SRM distributed a QuEChERS-based method where amitraz parent and its most important MRM -amenable metabolites containing the Analysis of “Amitraz (sum)” in samples with incurred residues -
