    Abstract: Various embodiments include methods and apparatuses to reduce false-particle counts in a water-based condensation particle counter (CPC). In one embodiment, a cleanroom CPC has three parallel growth tube assemblies. A detector is coupled to an outlet of each of the three parallel growth tube assemblies, and is used to compare the particle concentrations measured from each of the three growth tube assemblies. An algorithm compares the counts from the three detectors and determines when the particles counted are real and when they are false counts. Any real particle event shows up in all three detectors, while false counts will only be detected by one detector. Statistics are used to determine at which particle count levels the measured counts are considered to be real versus false. Other methods and apparatuses are disclosed.

  • Patent number: 10209100
    Abstract: A fiber measurement device for measuring a physical quantity by a fiber and a method for shaping a pulse of electromagnetic radiation are disclosed. The fiber measurement device comprises an electromagnetic radiation source and an adjustment unit. The electromagnetic radiation source generates at least one pulse of electromagnetic radiation as primary electromagnetic radiation to be coupled into the fiber, and an adjustment unit. The adjustment unit, prior to, during or after application of the primary electromagnetic radiation to the fiber, adjusts a shape of the at least one pulse for at least partially compensating a deviation between a target shape and an actual shape of the at least one pulse.

  • Patent number: 10190962
    Abstract: Flow cytometer systems are provided having intermediate angle scatter detection capability. In some aspects, systems are provided that include an intermediate angle scatter (IAS) light detector positioned to measure intermediate angle scatter emitted from a flow cytometer. The system further includes a mask disposed across a portion of the IAS light detector and positioned between the flow cell and the IAS light detector to cover at least a central portion of the IAS light detector so as to block a diffraction pattern observed at the detector. In some instances, the diffraction pattern is created by a flat beam profile irradiating the sample. Methods are also provided for configuring a flow cytometer to block a diffraction pattern created by (1) a flat laser beam profile irradiating a flow cytometer liquid sample, or (2) a mismatched index of refraction between a sheath fluid and a liquid sample in a flow cytometer.

  • Patent number: 10094756
    Abstract: A particulate measurement system includes an ion generation section for generating ions by means of corona discharge; an electrification chamber for electrifying particulates contained in a gas under measurement; a measurement signal generation circuit for generating a measurement signal which correlates with the amount of the particulates; and a particulate amount determination section for determining the amount of the particulates. The particulate measurement system further includes a particle diameter estimation section for estimating the particle diameter of the particulates contained in the gas under measurement. The particulate amount determination section performs correction by multiplying the measurement signal or the amount of the particulates determined from the measurement signal by a coefficient relating to the ratio between the estimated particle diameter and a reference particle diameter.

  • Patent number: 9891160
    Abstract: A flow chamber, imaging objective, condenser and imaging light source as part of an optical system includes an oil-immersion objective and high numerical aperture condenser matched to a rectangular flow chamber. The oil-immersion objective and flow chamber include a high index of refraction immersion oil so as to enhance the optical resolution and optical coupling therethrough. The flow chamber is reinforced with stiffening wires that are arranged to extend above a surface of the sidewalls of the flow chamber so as to function as a barrier to leakage of the immersion oil away from the surface of the flow chamber.

  • Patent number: 9816926
    Abstract: A system, device and/or method for multiplex assays. In a particular, but non-limiting, example there is provided a multiplex array, such as a suspension array. Luminescence decay lifetimes are utilized for probes in a suspension array, and coding/decoding the codes from time-resolved spectra. Lifetime populations can be generated at distinct color bands. A novel temporal technique or dimension is applied over conventional spectral and intensity combinations, thereby expanding the multiplexing capacity of a suspension array. In one example form, the multiplexing capacity of a suspension array can be expanded to the order of about 58. This provides a reliable, high-throughput and relatively inexpensive solution for multiplex assays in various areas of application such as life sciences, data storage and security.

  • Patent number: 9435726
    Abstract: Apparatus are described for measuring the characteristics of colloidal particles suspended in transparent media by Dynamic Light Scattering (DLS) and Depolarized Dynamic Light Scattering (DDLS) into regions where conventional measurements are difficult or impractical. Matching the diameter of an illuminating beam and an intersecting diameter of a field stop image extends measurements into regions that include concentrated turbid suspensions that frequently appear so visually opaque that multiple scattering typically gives a falsely low estimate of particle size.
