Contemplated is a sensor system for use with a measuring device. The measuring device being of the type adapted to measure the volume of a desired solid component in a sample volume of a solid-liquid slurry obtained from either a carbon-in-pulp or carbon-in-leach process. The solid-liquid slurry comprises granular carbon particles, ore pulp, and water. The carbon-in-pulp or carbon-in-leach process includes at least one retention tank. The measurement device including: a receptacle for receiving the sample volume of the slurry; a screen provided in the receptacle for separating out the desired solid component from a remainder of the slurry. The solid component is retained in the receptacle to form a bed therein and the remainder is exhausted from the receptacle. The sensor system measures in either the retained solid component, or the exhausted remainder, or both one of: pH; dissolved oxygen; pulp density or carbon content.

A system and method for sorting sperm is provided. The system includes a housing and a microfluidic system supported by the housing. The system also includes an inlet providing access to the microfluidic system to deliver sperm to the microfluidic system and an outlet providing access to the microfluidic system to harvest sorted sperm from the microfluidic system. The microfluidic system provides a flow path for sperm from the inlet to the outlet and includes at least one channel extending from the inlet to the outlet to allow sperm delivered to the microfluidic system through the inlet to progress along the flow path toward the outlet. The microfluidic system also includes a filter including a first plurality of micropores arranged in the flow path between the inlet and the outlet to cause sperm traveling along the flow path to move against through the filter and gravity to reach the outlet.

The invention relates to a system and micro monitor apparatus, a space-, time-, and cost-efficient device to concentrate, identify, and quantify organic compounds in gas environments. The invention further relates to a method centered on gas chromatography for identifying and quantifying organic compounds in gas environments, using air as the carrier gas, without the need for a compressed pre-bottled purified carrier gas.

Equipment for the control of the industrial contamination of industrial components comprising at least one base frame; and an extraction unit/device/component of contaminating impurities from at least one industrial component, mounted on the base frame and provided with a washing unit/device/component of the industrial component by way of an operating fluid adapted to remove the contaminating impurities from said industrial component, the operating fluid mixing with the contaminating impurities to obtain an operating mixture following the washing of the industrial component; and a preparation unit/device/component of at least one analysis sample of the contaminating impurities removed from the industrial component starting from the operating mixture, wherein the equipment comprises an analysis unit/device/component of the analysis sample mounted on the base frame and adapted to detect at least one analytical data which is characteristic of the contaminating impurities.

A system for collecting and chemically analyzing water samples extracted from the soil to measure one or more analytes of interest such as soil nutrient levels of agricultural interest for increasing crop yield and quality in one use of the system. The system includes a sample collection probe (20) comprising a filter media (26) arranged to contact the soil when embedded therein and capture a water sample from the soil, and operably coupled to a sample processing sub-system (180) thereby collectively forming a sampling station (190). The sub-system (180) is configured to receive and analyze the water sample. A programmable probe controller (60) directs operation of the sample collection, processing, and chemical analysis in situ. A networked array (110) of sampling probes dispersed throughout the field may communicate wirelessly with at least one remote electronic device such as via the cloud computing (102). A modular version of a sampling probe (200) permits customized sampling at various soil depths.

A disposable cartridge for mitigating cross-contamination of fluid sample reagents. The disposable cartridge includes a cartridge body defining a syringe barrel having an barrel port operative to inject and withdraw assay fluids in response to the displacement of a syringe plunger. Furthermore, the disposable cartridge includes a rotor defining a plurality of assay chambers in fluid communication with the barrel port through one of a plurality of rotor ports disposed about the periphery of the rotor. Finally, the disposable cartridge includes a flow control system between the barrel and rotor ports which prevents cross-contamination of fluid sample reagents from one assay chamber to another assay chamber.

An analyzing system is provided. The analyzing system includes a fluid container defining a sample chamber where a sample is contained in the sample chamber, and a sensor including a transparent body with a reverse face and an obverse face where the obverse face having a nanostructured surface. The nanostructured surface includes a plurality of elongate nanostructures having a respective longitudinal axis that is disposed substantially perpendicularly to the obverse face. The analyzing system includes an excitation and detection apparatus that includes an excitation source for generating a beam of polarized radiation and a corresponding radiation detector where the sensor is coupled to the fluid container such that the nanostructured surface is exposed to the sample chamber, to the sample located therein.

Filtration apparatuses, kits, and methods for rapid isolation of intact, viable mitochondria from tissues are described with mitochondria isolated by differential filtration through nylon mesh filters. Mitochondria can be isolated in less than 30 minutes using the filtration apparatuses, kits, and methods described.

A method is provided for testing a non-centrifuged oronasopharyngeal fluid sample (22) taken from a human or non-human animal for the presence of a virus, the method including passing the non-centrifuged oronasopharyngeal fluid sample (22) through one or more porous filters (32, 1932) to separate epithelial cells from the non-centrifuged oronasopharyngeal fluid sample by size-based filtration. Thereafter, an extraction liquid is prepared by extracting cellular components of the epithelial cells separated from the non-centrifuged oronasopharyngeal fluid sample (22). Thereafter, the extraction liquid is tested for the presence of the virus. Other embodiments are also described.
