SPECTROMETER COMPRISING CAPACITIVE TRANSIMPEDANCE AMPLIFIER WITH OFFSET

Spectrometers including integrated capacitive detectors are described. An integrated capacitive detector integrates ion current from the collector (768) into a changing voltage. The detector includes a collector configured to receive ions in the spectrometer, a dielectric, and a plate arranged in an...

More Information
Summary:Spectrometers including integrated capacitive detectors are described. An integrated capacitive detector integrates ion current from the collector (768) into a changing voltage. The detector includes a collector configured to receive ions in the spectrometer, a dielectric, and a plate arranged in an overlapping configuration with collector on an opposite side of the dielectric. The detector also includes an amplifier (764). A capacitive detector with offset (776) is described.
