The present invention relates generally to an apparatus for identifying biological particles. More particularly, the present invention relates to a small apparatus for identifying biological particles, wherein in a single apparatus having a simple structure, a cleaning solution is suctioned to separate the biological particles from a filter and a sample solution is discharged, the discharged sample solution is injected into a plurality of ticket modules, and the biological particles are identified by image analysis for the ticket modules, thereby enabling miniaturization of the apparatus.

The present invention relates to a pellet holding device for feeding, comprising an angle bracket, the angle bracket having two planar parts connected to one another in an integral manner and forming an elongate fold between the two parts, and to a system for holding the pellets, which is capable of immobilizing one or more pellets against each of the two parts in the fold, the planar parts being optically transparent.

A centrifugal field-flow fractionation device is provided with a controller for controlling introduction of a liquid sample by a sample introduction part and rotation of the rotor by a motor. The controller rotates the rotor at a first rotational speed when introducing the liquid sample into a flow path. The first rotational speed is faster than a second rotational speed. Therefore, when a liquid sample is introduced into the flow path, high centrifugal force can be applied to the liquid sample, which can suppress the variation of the particles in the liquid sample introduced to the flow path. The controller rotates the rotor at the second rotational speed slower than the first rotational speed with the liquid sample flow in the flow path stopped. Therefore, it is possible to prevent the constant application of high centrifugal force to the liquid sample, thereby suppressing the increase in the length of time required for analysis.

The disclosed apparatus, systems and methods relate to technology that provides a method for the assessment of the polymerization of a sample, e.g., whole blood or blood plasma coagulation, by a non-contact acoustic tweezing device via the application of a sweeping frequency to the levitating sample and the corresponding assessment of extracted sample parameters.

The invention relates to a method and device for simultaneously measuring mass concentrations of particulates with different sizes. The method detects particulates within different size ranges in air based on laser scattering and can eliminate cross interference between the particulates within different size ranges. The device is simple in structure, can realize on-line simultaneous measurement of PM1.0, PM2.5 and PM10 with high measurement precision and low cost.

A method for monitoring a property of nanoparticles in a flowing suspension comprises providing a sample comprising a flowing suspension. The method further comprises non-invasively monitoring a size distribution of nanoparticles of the flowing suspension using Fourier domain low-coherence interferometry, FDLCI, wherein the monitoring comprises deriving a time and optical path length resolved LCI light scattering signal l(t,z) from time resolved LCI wavelength spectra of interference and deriving information indicative of the size of the particles in the sample based on said time and optical path length resolved LCI light scattering signal using optical path length resolved temporal autocorrelation functions or optical path length resolved frequency power spectra of the spatiotemporal FDLCI signal.

A microfluidic device can include an upstream passage, a sample passage, a bifurcating passage, and a combining passage. The upstream passage can be configured to provide a focusing stream. The sample passage can be configured to provide a sample stream. The bifurcating passage can include a specified bifurcating flow resistance. The combining passage can be configured to create a combined stream from the focusing stream and the sample stream, where the focusing stream can direct the sample stream away from the upstream passage and toward the bifurcating passage. A first portion of the combined stream can be discharged through the bifurcating passage. The main discharge can be configured to discharge a second portion of the combined stream. The main discharge can include a main discharge resistance that is selectable to vary the main discharge resistance relative to the bifurcating flow resistance.
