  • Patent number: 10192730
    Abstract: A method of operating an electrostatic trapping mass analyzer, comprising: introducing a sample of ions into a trapping region of the mass analyzer, wherein a trapping field within the trapping region is such that the ions exhibit radial motion with respect to a central longitudinal axis of the trapping region while undergoing harmonic motion in a dimension defined by the central longitudinal axis, the frequency of harmonic motion of a particular ion being a function of its mass-to-charge ratio; superimposing a modulation field onto the trapping field within the trapping region, the modulation field acting to either increase or reduce the harmonic motion energies of the ions by an amount varying according to the frequency of harmonic motion; and acquiring a mass spectrum of the ions in the trapping region by measuring a signal representative of an image current induced by the harmonic motion of the ions.

  • Patent number: 10175263
    Abstract: A sample vessel retention mechanism for an inverted microscope having an optical objective and a scanning probe microscope (SPM) head. The inverted microscope includes a platform for supporting a sample vessel, in which is formed an aperture sized to provide a passage for the objective of the inverted microscope to approach the sample vessel from below. The retention mechanism provides a vacuum region formed in the platform, with the vacuum region being barometrically coupled with a vacuum generator. Establishment of a vacuum in the vacuum region prevents or substantially reduces oscillation of the sample vessel floor in an operating frequency range of the SPM head.

  • Patent number: 10170275
    Abstract: Surface modification of a cryogenic specimen can be obtained using a charged particle microscope. A specimen is situated in a vacuum chamber on a specimen holder and maintained at a cryogenic temperature. The vacuum chamber is evacuated and a charged-particle beam is directed to a portion of the specimen so as to modify a surface thereof. A thin film monitor is situated in the vacuum chamber and has at least a detection surface maintained at a cryogenic temperature. A precipitation rate of frozen condensate in the vacuum chamber is measured using the thin film monitor, and based on the measured precipitation rate, the surface modification is initiated when the precipitation rate is less than a first pre-defined threshold, or interrupted if the precipitation rate rises above a second pre-defined threshold.

  • Patent number: 10161933
    Abstract: The invention provides methods of detecting an analyte by multi-stage mass spectrometry with improved S/N ratio. An analyte is labeled with a positively-charged mass tag to form a precursor ion that leads by anchimeric assistance to a greatly enhanced, analyte-characteristic first product ion that can, in turn, lead to a greatly enhanced, analyte-characteristic second product ion in a mass spectrometer. Either a three stage mass spectrometer (true MS3) or a two-stage mass spectrometer (MS2) operated in a pseudo MS3 mode can be used. The precursor ion is split via an anchimeric-assisted reaction to form a first product ion, which in turn can be fragmented to form the second product ion. The methods offer extreme ultrasensitivity, at the low amol level. The invention also provides anchimeric mass tags for use in the methods. A wide variety of previously undetectable analytes of biological or environmental origin can be detected and quantified.

  • Patent number: 10161959
    Abstract: An atomic force microscope acquires sample information by performing relative raster scanning between a cantilever and a sample across an XY-plane, while causing an interaction to be generated between a probe provided at a free end of the cantilever and the sample. The atomic force microscope includes a raster-scanning-information generator to generate raster scanning information, a raster-scanning controller to control the raster scanning based on the raster scanning information, and an interaction controller to control strength of the interaction based on the raster scanning information. The interaction controller relatively reduces the strength of the interaction, when a relative speed between the cantilever and the sample across the XY-plane of the raster scanning relatively decreases.

  • Patent number: 10149915
    Abstract: A nectar type bird feeder having an incorporated short-wavelength, ultraviolet light source adapted to illuminate the nectar contents and feeder internal surfaces. The ultraviolet light exposure functioning to significantly retard the growth of nectar spoiling micro-organisms and thereby to significantly extend the nectar freshness or service life. The ultraviolet light source may be built directly into the nectar feeder or configured as an add-on accessory. The preferred embodiment of the nectar feeder, ultraviolet light device will be solar powered and made to cycle on/off automatically. As hummingbirds are adapted to see UV-A light (300 nm-400 nm) the light source may be cycled on/off during the day to make the feeder visually conspicuous and thereby more attractive to the feeding birds.
