The invention relates to a method for determining the electrophoretic velocity of droplets of a first fluid in a second fluid, the method comprising: providing a first capillary (3′) having an outlet positioned in a first channel (3); providing a stream of the first fluid in the first capillary and providing a stream of the second fluid in the first channel external to the first capillary, so as to generate droplets of the first fluid in the second fluid at the outlet of the first capillary; transporting the droplets to an observation area (200) in a second channel (11); applying an electric field to the observation area of the second channel; and measuring the velocity of the droplets in the observation area. The invention also relates to a device for determining the electrophoretic velocity of droplets of a first fluid in a second fluid.

The present invention provides a connector for use in a beverage dispense system, the connector defining a conduit for connecting a beverage line to a beverage supply. The connector comprises an electrical sensor (e.g. a capacitive sensor) for measuring an electrical parameter of a beverage within the connector conduit. The electrical parameter and/or changes in the electrical parameter can be used to detect bubbles in the beverage and/or identify the type/brand of beverage.

Nanofluidic flow cells and systems for single-molecule nanoconfinement and imaging of molecules in a fluid are described. The nanofluidic flow cell comprises a bottom substrate bonded to a top substrate, microchannels and a central chamber carved in the bottom or top substrate. The microchannels and the central chamber define an empty space into which a fluid can flow. The microchannels extend on opposite side of the central chamber, each microchannel comprising a central portion crossing the central chamber and a pair of arms extending outside the central chamber, these arms comprising a fluid port positioned at opposite ends of the microchannel and outside the central chamber. The central chamber comprises a nanoconfinement and imaging area including carved nanostructures configured for single-molecule nanoconfinement. Also described are nanofluidic chips, methods of confinement, pneumatic-based nanofluidic systems and manifold assembly for the nanofluidic flow cell.

Described herein are devices and methods for high throughput purification of particles. In some cases, methods and devices described herein can be used to remove erythrocytes and purify leukocytes and raise the quality of umbilical cord blood and other transplant grafts, thereby significantly improving patient outcomes.

This technology relates in part to optical methods for analyzing particles, including nanoparticles, thereby determining their presence, identity, origin, size and/or number in a sample of interest.

Various embodiments include methods and systems to dilute a sampled particle-laden aerosol stream in a recirculating type of aerosol diluter system. In one embodiment, a system to dilute a sampled aerosol stream includes an aerosol sample inlet. A primary diluter device includes a first inlet to receive the aerosol stream and a second inlet to receive a filtered portion of the aerosol stream and combining the filtered portion with an additional sampled aerosol stream. A flow diverter device splits at least the sampled aerosol stream into a first portion of the sampled aerosol stream and a remaining portion of the sampled aerosol stream. A filter receives the remaining portion of the sampled aerosol stream and provides a filtered aerosol stream to the second inlet of the primary diluter device. Other methods and apparatuses are disclosed.

Electronic component, in particular a sensor (1), in particular for detecting particulate matter, comprising: an electronic member, a housing (2) in which the electronic member is placed, said housing (2) comprising at least one functional opening (3a; 3b; 3c), characterised in that at least one protective shield (6a, 6b) is arranged on the housing (2) in order to protect the electronic member from the intrusion of material into the housing (2), in particular fluids or solids, which could pass through the functional opening (3a, 3b, 3c).

A sample dispersing device contains a container inside of which a dispersal chamber where a power sample is dispersed is formed, and an introducing mechanism that introduces a gas containing the powder sample from the outside of the container into the dispersal chamber based on a pressure difference between the inside and the outside of the container. The introducing mechanism contains an introduction pipe where the gas containing the powder sample flows, and several restrictors arranged in the introduction pipe.
