Abstract: An ELIT includes voltage sources (1101), switches (1102), a first set of electrode plates (1110) aligned along a central axis, and a second set of electrode plates (1120) aligned along the central axis with the first set. A first group of plates (310, 320; 810, 820) of the first set and the second set is positioned to trap ions within a first path length (340, 940). A second group of plates (410, 420) of the first set and the second set is positioned to trap ions within a shorter second path length (440, 1040). The switches select the first path length by applying voltages from the voltage sources to the first set and the second set that cause the first group of plates to trap ions within the first path length. Alternatively, the switches can select the second path length by applying voltages that cause the second group of plates to trap ions within the second path length.

Abstract: An ion guide defining a guide axis receives ions. The ion guide applies a potential profile that includes a pseudopotential well to the ions using an ion control field. The ion control field includes a component for restraining movement of the ions normal to the guide axis and a component for controlling the movement of the ions parallel to the guide axis. The ion guide sequentially injects the ions with the same ion energy and in decreasing order of m/z value into an ELIT aligned along an ELIT axis to focus the ions irrespective of m/z value at the same location on the ELIT axis within the ELIT at the same time by varying a magnitude of the pseudopotential well. The ELIT can trap the focused ions using in-trap potential lift or mirror-switching ion capture.

Abstract: An MCP detector (620) receives an ion packet along an ion path (601) of mass spectrometer through a hollow central cylindrical tube (621) of the MCP detector. The MCP detector includes coaxial rings (622) of MCPs surrounding the hollow central cylindrical tube. The MCP detector transmits the ion packet along the ion path to an ELIT (610) through holes in the center of a first set of reflectron plates (613) of the ELIT to oscillate the ion packet between the first set and a second set of reflectron plates (614) of the ELIT. The ELIT transmits the oscillated ion packet back to the MCP detector along the ion path through the holes of the first set. The MCP detector detects ions of the oscillated ion packet that are radially deflected from the ion path using the rings of MCPs. The MCP detector allows ions to be transmitted to or from either port of the ELIT.

Abstract: A mass spectrometer is operated to simultaneously measure precursor and production data over a number of acquisitions. For each acquisition, the following steps are performed. Ion transfer optics inject ions from an ion beam into an ELIT causing the ions to oscillate axially between two electric fields produced by two the sets of reflectrons. The ELIT measures a time domain image current of the oscillating ions from ion injection to a total acquisition time, Tacq1, and fragments the oscillating ions at one or both turning points of the oscillating ions adding product ions to the oscillating ions. The fragmentation is performed at a delay time relative to the ion injection that is increased by a time increment in each subsequent acquisition making the fragmentation dependent on ion position. The measured time domain image current is stored as a row or column of a two-dimensional matrix.

In various embodiments, de-identified data may be received (1102) that includes de-identified data set(s) associated with subject(s) that is generated from raw data set(s) associated with the subjects. Each of the raw data set(s) may include identifying feature(s) that are usable to identify the respective subject. At least some of the identifying feature(s) may be absent from or obfuscated in the de-identified data. Labels associated with each of the de-identified data sets may be determined (1104). At least some of the de-identified data sets may be applied (1108) as input across a trained machine learning model to generate respective outputs, which may be compared (1110) to the labels to determine a measure of vulnerability of the de-identified data to re-identification.
