The present disclosure includes methods and systems for monitoring real time quality of specialty fluids within one or more specialty fluid containers stored within one or more gas cabinets. The methods and systems monitoring the real time quality of the specialty fluids may utilize an analyzer and sampler to perform one or more tests on the specialty fluids to determine the quality of the specialty fluids in real time. The data collected by the analyzer and sampler may be stored on and processed with the on-line data system to determine if the quality of the specialty fluids is sufficient to be introduced to one or more workpiece processing tools for processing one or more workpieces. The data collected may be compared to a manufacturer technical specification with respect to the specialty fluid to determine if the manufacturer is providing specialty fluids of sufficient quality.

An evaporation closed chamber for detecting hazardous substance, having a closed chamber, an orifice plate, a pressure plate, a drive device and an elastic film, the orifice plate is mounted on any surface(s) of the closed chamber, the elastic film is arranged on the outer side of the orifice plate, the pressure plate is arranged on the outer side of the elastic film, and the drive device is in transmission connection with the pressure plate to drive the pressure plate to move forwards and backwards to press the elastic film against the orifice plate. The elastic film expands with the increase of internal temperature of the closed chamber and shrinks with the temperature decrease of the closed chamber such that the gas in the closed chamber can be timely compensated; the orifice plate prevents hazardous substance from leaving on the gas compensation device to influence test accuracy.

Embodiments herein include a method for detecting a brain condition in a subject. The method can include obtaining a breath sample from the subject and contacting it with a chemical sensor element, where the chemical sensor element includes a plurality of discrete graphene varactors. The method can include sensing and storing capacitance of the discrete graphene varactors to obtain a sample data set and classifying the sample data set into one or more preestablished brain condition classifications. Other embodiments are also included herein.

Provided herein are methods and devices that allow for efficient management of many different sampling locations within a facility. A method for operating a biological sampler, a particle counter, and like air sampling, analysis, and/or monitoring equipment or instrumentation is described, such as by sampling an environment at a sampling position with the biological sampler and storing sample data and other useful information in memory in association with unique identifier(s) including sampling location(s) for the samples. Also provided are associated devices for carrying out the methods.

Disclosed herein are methods and systems for capture and measurement of a target component. A fluid sampling tool for sampling fluid from a subterranean formation may include a sample chamber having a fluid inlet, wherein the sample chamber is lined with a coating of a material that can reversibly hold a target component.

An analytical inspection system for determining concentration of mobile hydrogen of and/or on surfaces of a metallic object can include: a vacuum furnace; a hydrogen sensing device; and/or a flow path from the furnace to the sensing device. The sensing device can be configured to detect and/or measure the mobile hydrogen at levels less than or equal to 1 part per million (ppm). An analytical inspection method for determining concentration of mobile hydrogen of and/or on surfaces of a metallic object can include: placing the object into a vacuum furnace; drawing a vacuum in the furnace; and/or simultaneously heating the metallic object in the furnace and measuring a quantity of the mobile hydrogen released from the object using a hydrogen sensing device. The sensing device can be configured to detect and/or measure the mobile hydrogen at levels less than or equal to 1 ppm.

A detection device includes a transfer device to travel along a rail while gripping a carrier, and a detection structure mounted on the carrier. The detection structure includes a collector to suck in air, a detector connected to the collector, the detector including a plurality of sensors, a plurality of sensor control boards receiving electrical signals from the plurality of sensors, the plurality of sensor control boards generating, based on the electrical signals, type data and concentration data regarding pollutants included in the air sucked in by the collector, and a communication control board connected to the plurality of sensor control boards.

A sampling probe, an automatic sampling device, and a container detection system are provided. The sampling probe includes: a mounting base; a housing mounted on the mounting base, a first accommodation chamber having an opening being defined in the housing, and an exhaust hole in communication with the first accommodation chamber and outside of the housing being formed in the housing; a coupling portion formed on an outer edge of the opening of the first accommodation chamber and formed to be hermetically coupled with an air outlet of a container; and a suction device mounted on the housing and configured to suck gas in the container into the first accommodation chamber through the air outlet.
