A device to detect pathogens and/or analytes in a test sample is designed to include a core, which may have first and second chambers. The first chamber is designed to accept a combination of a test specimen and a buffer liquid. A piston is designed to slideably engage into the first chamber of the core, wherein the end of the piston may engage with the bottom of the first chamber and be capable of grinding the test specimen. A plunger is designed to slideably engage with the second chamber of the core, and is in fluid communication with the first chamber. An assay section is attached to the core, and is in fluid communication with the second chamber. The assay device is designed to include a test strip that is capable of detecting and indicating the presence of pathogens and/or analytes in the combination of the test sample and buffer liquid.

The present invention relates to a method for liquefying respiratory samples, such as sputum samples. Samples of this type are characterized in that they can be highly viscous or semisolid, which means that to detect pathogenic microorganisms in them, they require prior treatment in order to make them more liquid and homogeneous. The liquefaction method proposed in the present innovation enables pathogenic microorganisms that cause respiratory infections to be subsequently detected.

An embodiment for a microfluidic device is provided. The device comprises two areas, arranged side-by-side, and a trigger channel. They include a first area, which is delimited by a first liquid pinning barrier, and a second area, which is delimited by a second liquid pinning barrier. The latter extends parallel to the first liquid pinning barrier to delimit a corridor. The trigger channel extends through the corridor between the two areas. In addition, the trigger channel connects the first liquid pinning barrier with the second liquid pinning barrier, allowing a first liquid pinned at the first liquid pinning barrier and a second liquid pinned at the second liquid pinning barrier to be contacted, each, by a reverse flow of the second liquid in the trigger channel and thereby start mixing at a level of the corridor, in operation. The invention is further directed to related methods of operation.

A method for processing a sample of a cell culture composition includes diluting the sample followed by filtering the diluted sample, wherein the dilution may be at least 10 parts by volume of a diluent to one part sample, and the filter may be a porous membrane with a molecular weight cutoff of less than 20,000 Daltons. The dilution may be carried out at a multiple-port dilution valve having a first condition and a second condition. The sample may be mixed with the diluent at a predetermined dilution ratio when the dilution valve is in the second condition.

Methods, devices, and systems are disclosed for releasing a sample from a carrier medium. A method of releasing a sample from a carrier medium comprises treating a sample on a carrier medium with a first organic reagent, wherein when the sample contains at least one inorganic salt, the first organic reagent binds to a cation of the inorganic salt to produce both a first volatile compound and an isolated anion of the inorganic salt; treating the sample on the carrier medium with a second organic reagent, wherein the second organic reagent reacts with the isolated anion to produce a second volatile compound; and releasing the treated sample from the carrier medium, wherein when the first and the second volatile compounds are produced, the releasing step releases at least one of the first and second volatile compounds from the carrier medium.

The implementations described herein generally relate to 30 nm in-line liquid particle count testing equipment which analyses and cleans semiconductor processing equipment. More specifically, the implementations described relate to a system for diluting, analyzing, and modifying fluids to enable the observation of the contents of the fluids. A dilution sampling tool is coupled with a liquid particle detector for reading the contents of an extraction solution containing particles from semiconductor processing equipment, such as a liner, a shield, a faceplate, or a showerhead, in a cleaning tank. As such, accurate liquid particle readings may be had which reduce oversaturation of the particle detector.
