  • Patent number: 10684308
    Abstract: Techniques are disclosed for stabilizing soft specimen traditionally considered too fragile for APT instruments. These specimens include biological samples, polymers and other fragile materials. For this purpose, a protective structure is disclosed that surrounds the sides of the specimen by supporting walls while only exposing the very end or terminus of the specimen to the electrostatic field of the APT instrument. The protective structure may take the form of a nanoscale conical grinder which continually machines the specimen to regenerate the terminus of the specimen in-situ. Alternately, the protective structure may take the form of a nanopipette in which the specimen is first frozen before undergoing field evaporation together with the tip of the nanopipette. Heretofore only routinely possible for rigid and hard materials, the design thus extends APT analysis to produce three-dimensional atomic-scale maps of soft specimens.

  • Patent number: 10656127
    Abstract: A data independent acquisition method of mass spectrometry for analysing a sample as it elutes from a chromatography system is disclosed. The method comprises the steps of: ionising the sample to produce precursor ions, selecting a precursor mass range for the sample to be analysed, performing a plurality of MS1 scans and performing at most two sets of MS2 scans. Each of the MS1 scans uses a mass analyser operated at a first, relatively higher resolution, for identification and/or quantitation of the sample in the MS1 domain across the precursor mass range. The set of MS2 scans comprises performing MS2 scans of fragmented mass range segments performed with the mass analyser, operated at a second, relatively lower resolution. In the method, the MS1 scans are interleaved throughout the performing of the set of MS2 scans such that the MS1 scans provide a mass chromatogram of the sample.

  • Patent number: 10593531
    Abstract: An acceleration voltage generator generates a high-voltage pulse applied to a push-out electrode, by operating a switch section to turn on and off a high direct-current voltage generated by a high-voltage power supply. A drive pulse signal is supplied from a controller to the switch section through a primary-side drive section, transformer, and secondary-side drive section. A primary-voltage controller receives a measurement result of ambient temperature of the acceleration voltage generator from a temperature sensor, and controls a primary-side power supply to change a primary-side voltage according to the temperature, thereby adjusting the voltage applied between the two ends of a primary winding of the transformer. The adjustment made on the primary-side voltage changes a slope angle of rise of a gate voltage in the MOSFET, and enables a correction to a discrepancy in the timing of the rise/fall of the high-voltage pulse caused by change in ambient temperature.
