Enhanced Charge-Sensitive Amplifier Performance Leads to Substantially Reduced CD-MS Measurement Times for Charge State Resolution
In charge detection mass spectrometry (CD-MS) ions are trapped in an electrostatic linear ion trap (ELIT) where they oscillate back and forth through a conducting cylinder. The oscillating ions induce...
