Fine particle measurement device

A fine particle measurement device includes a support stand (20) that has a groove (F) extending in a predetermined direction and is configured to support in the groove an observation container (10), which has an elongate shape and accommodates a liquid sample containing a fine particle therein such that an extending direction of the groove (F) coincides with a longitudinal direction of the observation container (10); and an imaging unit (40) that is configured to capture an image of the fine particle in the observation container (10) at a position where the support stand is out of a field of view, the observation container (10) being supported by the support stand (20).

Antimicrobial particle detectors

The invention generally provides systems and methods for particle detection for minimizing microbial growth and cross-contamination in manufacturing environments requiring low levels of microbes, such as cleanroom environments for electronics manufacturing and aseptic environments for manufacturing pharmaceutical and biological products, such as sterile medicinal products. In some embodiments, systems of the invention incorporate a housing having an outer surface being a first antimicrobial surface and a touchscreen being a second antimicrobial surface. In some embodiments, substantially all of the outer surfaces of the system are antimicrobial surfaces. In some embodiments, the first antimicrobial surface may comprise an Active Screen Plasma alloyed layer. In some embodiments, the housing may comprise a molded polymer substrate and a metal coating layer bonded to the molded polymer substrate such that at least some exterior surfaces of the housing are metal coated surfaces.

KIT AND METHOD FOR DETECTING DROPLET DRIFT OR DEPOSITION CHARACTERISTICS OF SPRAY

A kit is employed in the method for detecting droplet drift or deposition characteristics of spray. The detection kit includes detection membranes carrying immobilized probes, transition probes capable of specifically binding to the immobilized probes, and biotinylated chromogenic probes capable of specifically binding to the transition probes. The transition probes are added to the agricultural spray as tracers. After spraying, the sprayed transition probes specifically bind to the immobilized probes on the detection membranes. The biotinylated chromogenic probes are added to bind to the transition probes through hybridization. After the chromogenic treatment, the deposition volume of droplets is determined according to the color depth, and the droplet parameters are determined according to the position and size of chromogenic spots. The method can qualitatively detect the droplet drift or deposition distribution of spray, and to determine the droplet drift or deposition volume and the droplet coverage density and droplet size.

Characterization of a phase separation of a coating composition

A method for detecting a phase separation of a waterborne or solvent-borne or solvent-free coating composition includes providing the coating composition in a receptacle; providing a measurement instrument for receiving the receptacle, the measurement instrument including a measurement probe; controlling the measurement instrument to a) displace the measurement probe through the coating composition along a predefined measurement path with a predefined speed profile, the predefined measurement path extending along a length axis of the receptacle, b) acquire a force-displacement profile by measuring a force exercised on the measurement probe while the probe is being displaced along the predefined measurement path with the predefined speed profile; processing the force-displacement profile for detecting at least one phase separation of the coating composition; and outputting a detection result.
