Abstract: Certain embodiments described herein are directed to detectors and systems using them. In some examples, the detector can include a plurality of dynodes, in which one or more of the dynodes are coupled to an electrometer. In some instances, an analog signal from a non-saturated dynode is measured and cross-calibrated with a pulse count signal to extend the dynamic range of the detector.
