CE-MS services permit different type of searches depending on the input data. It allows searches using the effective mobilities, the migration times or the relative migration times. The experimental conditions shall be introduced in order to refine the search. The buffer used (formic or acetic acid), the polarity (direct or inverse), the capillary length and the capillary voltage. The next list briefly describes each service:

• CE-MS experimental RMT search: mz/s and RMTs respecting methionine sulfone or paracetamol. The information was collected experimentally in positive ionization mode. For more information, check the CMM manual.
• CE-MS effective mobility search: mz/s and effective mobilities collected experimentally in both positive and negative ionization mode. For more information, check the CMM manual.
• CE-MS absolute Migration Times search using 1 marker: mz/s and MTs. The capillary length (mm), the capillary voltage (kV) and the migration time of 1 marker present in the database shall be introduced in order to predict the MTs of all the database compounds. The prediction is based on the effective mobilities acquired experimentally in both positive and negative ionization mode.
• CE-MS absolute Migration Times search using 2 markers: mz/s and MTs. The migration time of 2 markers present in the database shall be introduced in order to predict the MTs of all the database compounds. The prediction is based on the effective mobilities acquired experimentally in both positive and negative ionization mode.
• CE-MS relative Migration Times search using 1 marker: mz/s and RMTs regarding the compound used by the user and present in the database. The capillary length (mm), the capillary voltage (kV) and the migration time of 1 marker present in the database shall be introduced in order to predict the MTs of all the compounds in the database. The prediction is based on the effective mobilities acquired experimentally in both positive and negative ionization mode.
• CE-MS relative Migration Times search using 2 markers: mz/s and RMTs regarding the compound used by the user and present in the database. The migration time of 2 markers present in the database shall be introduced in order to predict the MTs of all the database compounds. The prediction is based on the effective mobilities acquired experimentally in both positive and negative ionization mode.
• CE-MS targeted effective mobility search: mz/s, effective mobilities and in-source product ions. The effective mobilities were collected experimentally in both positive and negative ionization mode. The product ions were collected from standards using both 100V and 200V in the ionization source. For more information, check the CMM manual.
• CE-MS targeted experimental RMT search: mz/s and RMTs respecting methionine sulfone or paracetamol and in-source product ions. The experimental RMTs were collected experimentally in both positive ionization mode. The product ions were collected from standards using both 100V and 200V in the ionization source. For more information, check the CMM manual.
