  • Patent number: 11946852
    Abstract: Provided herein are optical systems and methods for detecting and characterizing particles. Systems and method are provided which increase the sensitivity of an optical particle counter and allow for detection of smaller particles while analyzing a larger fluid volume. The described systems and methods allow for sensitive and accurate detection and size characterization of nanoscale particles (e.g., less than 50 nm, optionally less than 20 nm, optionally less than 10 nm) for large volumes of analyzed fluids.
    Type: Grant
    Filed: December 16, 2021
    Date of Patent: April 2, 2024
    Assignee: PARTICLE MEASURING SYSTEMS, INC.
    Inventors: Daniel Rodier, James Lumpkin, Dwight Sehler, Brian Knollenberg

  • Patent number: 11268930
    Abstract: Described herein are monitoring systems and methods, including for airborne molecular contamination (AMC), that combine a sampler, such as an impinger or sorbent tube with a real time analyzer, such as an ion mobility spectrometer (IMS) or optical particle counter. The system may allow for selective sampling in which the sampler is only exposed to the target fluid during periods in which the real time analyzer detects analytes, such as molecular contamination or particles, meeting particular criteria such the composition and/or concentration of analytes. The invention also includes impinger systems having a sampler reservoir comprising an anion leaching resistant material characterized by low anion leach rates in the presence of deionized water.

  • Patent number: 10859487
    Abstract: The systems and methods provided herein relate generally to the improvement of data quality in optical liquid particle counters and control of optical particle counters to achieve longer expected lifetime, for example by avoiding damage caused by electromagnetic radiation and heat. The systems and methods incorporate sensors which characterize the fluid flowing through the flow cell, thereby enhancing accuracy and reducing the number of false positives.
