A quadrature method for producing circularly polarized excitation for selective detection of positive or negative ions has been proposed for Fourier-transform ion cyclotron resonance mass spectrometry. The new technique achieves the same post-excitation ion cyclotron orbital radius at half the excit

Previous masz spectrometers based on the ion cyclotron resonance principle have employed continuous excitation (smgle-pube or frequency-sweep), with detection during (frequency-sweep) or after (single-pulse or frequency smcep) the excitation. The present paper introduces an exper-knent in uhich an i
