In the present disclosure, the size of the semipermeable membrane is no longer limited by the sampling device, and therefore the difficulty of increasing the area of the semipermeable membrane is reduced.

Provided is a measurement device, including: a droplet forming part configured to form aerosol-like liquid droplets from a liquid in which a fluorescent substance specifically bondable to detection target particles and a specimen are mixed with each other; a droplet sorting part configured to sort droplets having a diameter smaller than a predetermined value from the droplets formed by the droplet forming part; and a measurement part configured to irradiate light onto the droplets sorted by the droplet sorting part and configured to measure the fluorescence intensity of the droplets.

Apparatus and methods for sampling air-borne particles. According to one embodiment a nozzle is used to generate a jet of fog that includes a gas and liquid droplets. The jet of fog is formed by the nozzle in a way to cause particles in the air surrounding the jet of fog to be drawn into the jet of fog and to further cause the particles to aggregate with the liquid droplets inside the jet of fog. A sample collecting surface is located opposite and spaced apart from an outlet of the nozzle. The sample collecting surface is preferably sloped so that the liquid sample can be forced by gravity off the collecting surface and into a liquid sample container. Inside the jet of fog and on the sample collection surface the liquid droplets merge with one another to form larger sized droplets that are collectable in the liquid sample container.

A particulate matter measuring apparatus including an inlet for introducing air, a cyclone means fluidly connected to the inlet, the cyclone means adapted to remove particles of a predetermined size from the air, a particle detector to detect particulate matter in the air and a pump to move the air from the inlet, through the cyclone means and through the particle detector, wherein the particle detector has a laser diode to shine laser light through the air and a detector angled at between 115 to 140 relative to the direction of the laser light to detect an amount of laser light scattered by particulate matter in the air.

A system for collecting particles having a suctioning device and a chamber for centrifugating and collecting particles. The centrifugation chamber having a guiding edge as well as an air inlet and an air outlet. The device having an assembly including an air suctioning conduit, a member including a guiding and receiving system, at least one guiding edge of the chamber, the member being mobile relative to the conduit between a first position, wherein the at least one guiding edge can be guided and received in the guiding and receiving system and a second position for collecting particles, where the air outlet of the chamber is applied on an end of the conduit.

A system for sampling aerosols, for purpose of predictive analyses, from fractured test specimens is provided. The system includes a test enclosure, a load apparatus, and an aerosol sampling pack in fluid communication with the test enclosure. The test enclosure is sized to partially or completely receive the test specimen therein, and the load apparatus is configured to impart a mechanical load (e.g., tension, bending, torsion, shear forces, or compression) on the test specimen. The aerosol sampling pack receives solid aerosols that are generated upon fracture of the test specimen.

A cyclonic filter separator with liquid block capabilities formed to separate liquids in a fluid stream for on-stream and spot sampling of natural gas or the like, particularly pressurized process gas having liquid entrained therein, otherwise referenced as multiphase or wet. The present invention incorporates a liquid block apparatus downstream the cyclonic separator to provide to further prevent liquid passing therethrough. A coalescing filter or the like (shown in cylindrical, cartridge form) may be situated downstream the liquid block to remove entrained liquids from the fluid stream, providing three liquid separation systems in series, ensuring a dry gas sample stream for analysis or the like.
