Fourier-transform ion cyclotron resonance (FT-ICR) mass spectrometry (MS) remains the technique of choice for the analysis of intact proteins from complex biological systems, i. accuracy, improved transmission intensity, and improved dynamic range were acquired using this fresh cell with increased post-excitation cyclotron radii. The improved cyclotron radii correspond to improved ion kinetic energy and collisions… Continue reading Fourier-transform ion cyclotron resonance (FT-ICR) mass spectrometry (MS) remains the technique
