7 ptimal Workflow for Target analysis Quantification of all regulated compounds in one shot can compromise robustness and sensitivity of the system. Multiresidue methods can show limits depending on chromatography. A previous screening analysis, using identification techniques, allows to have a list of compounds which are present on the sample. Quantification of LY those compounds which were positive on the screening analysis is more robust, sensitive and reliable than trying to afford all regulated compounds at the same time. Screening Confirmation Quantification

71 Harness the full power of AM MS/MS MS/MS Structural Correlation (MSC) TF MS Generate Formula MS/MS Q-TF MS/MS Correlate Structure Confirm structures Unknown analysis Correlate observed AM MS/MS fragments into proposed structure Using novel systematic bond breaking approach, based on work from Alastair Hill, RCM 2005, 9, -8) The fewer bonds need to be broken, the higher the probability that a proposed fragment will show in the MS/MS spectrum. Breaking double bonds gets assigned a higher penalty than breaking a single bond Same scientific approach as WATERS Mass Fragment Much faster than MassFragment Unique: Can do parallel processing of hundreds of structures! Availability of MassHunter MSC Will ship with MassHunter B as a Tool on Supplemental Disk for FREE! Page 7

72 MassHunter MS/MS Structural Correlation (MSC) USE CASE : Confirm proposed structures Provides highest confidence in confirmation of proposed structures in minutes instead of hours USE CASE : Assigns fragment ions to substructures of a proposed parent structure Metabolite ID Metabolomics Applied Markets Screening Page 72

73 MassHunter MSC USE CASE Confirm proposed structure via accurate mass MS/MS MFG score based on accurate mass of each MS/MS fragment ion and its neutral loss from precursor Total score very high (97.) due to high individual scores and explanation of all high intensity fragment ions. All fragment ions exhibit very high scores (few bond breakages), but multiple candidate isomeric structures are possible, e.g. 4 for MSC calculates molecular formulas (MFG) based on precursor and fragment ions (unique!). The correct formula has a lower precursor score, because only two isotopes were put in and the abundance could not be accurately determined by measuring the printout! MSC calculates all possible subformulas for each fragment ion with mass deviation in mda Showing individual substructures with penalties for Beta Jan 20 Release Mid 20 Page 7

74 MassHunter MS/MS Structural Correlation (MSC) USE CASE 2: Aid true unknown analysis Help identify true unknown compounds STEP : Generate as few as possible molecular formulas from unknown compounds using MS and MS/MS STEP 2: Retrieve all possible structures for the high scoring formulas STEP : Run MS/MS Structural Correlation in batch mode on all formulas => unique to MassHunter MSC STEP 4: Review structures from high scoring structures!
