MassHunter OptimizerAutomated MRM Method DevelopmentSoftware for 6400 series Triple Quad LC/MSCompound-specific optimization for MRM experiments Selection and optimization of precursor ion and fragment ions Support of optimization with multiple methods (e.g. pos/neg) Creation of a compound database with optimized resultsWITHOUT Optimizer: Manual optimization for multiple compounds WEEKS of tedious interactive work!WITH Optimizer: Optimization can be fully automated One or two days unattended work!

MassHunter MS/MS Method OptimizerBasic StepsRun 1: The precursor adducts (H , Na , etc) andcorresponding Fragmentor value are optimized. Basedon this, the optimum precursor mass and Fragmentorvalue are set.Run 2: Coarse product ion scan finds the largest 4 productions with corresponding Collision Energy. As a default0, 10, 20, 30, 40 volt CE are surveyed.Run 3: Fine adjustment of each product ion to establishoptimal Collision Energy.

MassHunter OptimizerStep 1 – Setup Compounds Setup compounds manually or via import from XLS Provide either formula or molecular weight Optionally assign compounds to groups

MassHunter OptimizerStep 2 – Setup Precursor Ion Selection Define up to 4 adducts and/or charge states for each polarity Define exclusion of ions based on m/z or intensity

MassHunter OptimizerStep 3 – Setup Product Ion Selection Optimizer will find the 4 most abundant product ions Define minimum product ion mass Define exclusion of ions based on m/z, intensity or neutral losses

MassHunter OptimizerStep 4 – Setup Optimization Parameters Setup Sample introduction mode– Manual or automatic infusion, Injection with or without column Select data file directory Select range and step size for Fragmentor and CE coarse and fine

MassHunter OptimizerStep 5 –View Results for Project Results for the project can be immediately viewed after optimization Results get also automatically written into the compound database
