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

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.
