Smart Operation






                     Creating an MRM analysis method requires determining the optimum transitions, collision energies, and other complicated   Smart MRM
                     parameters. Smart MRM, the method creation function, creates optimized analytical methods by using the transitions data in
                     the “Smart Database” file. When you want to perform MRM measurements of components not contained in the database, the   Automatic Method Creation
                     optimal transitions can be automatically searched for using the MRM Optimization Tool.
                                                                                                                                        The Smart MRM technology automatically creates methods with measurement times optimized for each component based on
                                                                                                                                        the Smart database. The Automatic Adjustment of Retention Time (AART) function incorporated in the system estimates
                                                                                                                                        retention times with high accuracy. When creating methods for simultaneous multicomponent analysis, the complicated process

                                                                                                                                        however, it is possible to automatically create methods in which data are acquired with high sensitivity only during the elution
                       Optimize MRM Transitions Automatically                                                                           time of the target components. In addition to MRM methods, SIM methods can be created.

                     Determining and optimizing MRM transitions for new compounds can require significant development time. The “MRM
                     Optimization Tool“ automates the process by collecting product ion scan data and finding the optimum collision energy for
                     each transition.
                     Once established, the transitions are registered to one of the Shimadzu “Smart Database” files, and the MRM or Scan/MRM
                     methods are created using Smart MRM.
