This primer covers a range of options which often require complementary equipment, such as syringe pumps, for efficient ionization. ESI is the most common form of ionization used for MS. 3 It employs ...

1. Some guidelines for methods to ionize samples: a. Electrospray Ionization (ESI): Samples ionized by ESI are introduced into the instrument in a solution of polar solvents via a spray at atmospheric ...

The Agilent 6545 Q-TOF mass spectrometer at the Western Illinois Mass Spec Center is equipped with the following interchangeable API sources: Dual Agilent Jet Stream (AJS) electrospray ionization (ESI ...

These ionization methods can tolerate impurities provided that the impurity peaks do not overlap the sample peaks. Samples may be either solid or liquid; however, highly volatile liquid samples will ...
