20130181125 | METHOD AND SYSTEM FOR INCREASING THE DYNAMIC RANGE OF ION DETECTORS - A mass spectrometer system can include a mass analyzer operable to mass transmit streams of ions to a detector in a mass dependent fashion for measurement of ion flux intensity. An ion attenuator can be located in the extraction region between the mass analyzer and detector, downstream of the mass analyzer, and can be operable to provide selective attenuation of the ion beam by attenuating ion flux intensity also in mass dependent fashion. Higher concentration ions can be selected and attenuated, while other lower concentration ions can be left unattenuated. Different ions can be attenuated to different degrees. Locating the ion attenuator downstream of the mass analyzer so that the ion beam is already mass differentiated when attenuated can avoid mass discriminatory effects associated with ion beam attenuators. Selective attenuation of only certain ions but not others can extend the dynamic range of the detector without necessarily sacrificing detector sensitivity. | 07-18-2013 |

20150142361 | High Dynamic Range Detector Correction Algorithm - Systems and methods are provided to perform dead time correction. An observed ion count rate is obtained using a non-paralyzable detection system of a mass spectrometer. The detection system includes an ion detector, a comparator/discriminator, a mono-stable circuit and a counter. The non-paralyzable detection system exhibits dead time extension at high count rates. The extension of the dead time occurs because the mono-stable circuit requires a rising edge to trigger and can only be triggered again after the output pulse from the comparator/discriminator has gone low. This allows a second comparator/discriminator pulse arriving just before the end of the dead time started by a first comparator/discriminator pulse to extend the dead time to the trailing edge of the second comparator/discriminator pulse. A true ion count rate is calculated by performing dead time correction of the observed ion count rate. | 05-21-2015 |

In some embodiments, the detector can operate at count rates of up to about 20 million counts per second without reaching saturation. Further, the lifetime of the detector can be extended. A variety of embodiments of systems, devices, and methods in conjunction with the disclosures are provided. | 11-12-2015 |
