The Orbitrap mass analyzer operates based on the principle of ion trapping and oscillation. Ions are injected into an electrostatic field created by a spindle-shaped electrode. These ions oscillate around the central electrode, and their oscillation frequencies are detected and converted into mass-to-charge (m/z) ratios. The high resolving power of the Orbitrap allows it to distinguish between ions with very close m/z values, making it ideal for complex sample analysis.
