  • ADVANCED SYSTEMS AND METHODS FOR INTERFEROMETRIC PARTICLE DETECTION AND DETECTION OF PARTICLES HAVING SMALL SIZE DIMENSIONS
    Publication number: 20240230509
    Abstract: The present invention relates to interferometric detection of particles and optical detection of particles having size dimensions less than or equal to 100 nm. Systems and methods are provided exhibiting enhanced alignment and stability for interferometric detection of particles and/or optical detection of particles having size dimensions less than or equal to 100 nm. Systems and methods are provided that include compensation means for mitigating the impact of internal and external stimuli and changes in operating conditions that can degrade the sensitivity and reliability of particle detection via optical methods, including interferometric-based techniques and/or systems for optical detection of particles having size dimensions less than or equal to 100 nm.
    Type: Application
    Filed: October 27, 2023

  • Thermal regulation of rotors during centrifugation
    Patent number: 11660617
    Abstract: The present invention provides centrifuges (e.g., analytical centrifuges) comprising a cooling assembly having a cooling surface disposed inside the centrifuge chamber and spaced apart from the rotor. The cooling surface disposed inside the centrifuge chamber, spaced apart from the rotor, and configured to exchange heat between the cooling assembly and the rotor, the thermal element thermally coupled to the cooling surface, and configured to control the temperature of the cooling surface.
