Abstract: A system for sampling a sample material includes a device for directing sample into a capture probe. The device for supplying sample material to the probe can be a device for radiating energy to the surface to eject sample from the sample material. A probe includes an outer probe housing having an open end. A liquid supply conduit has an outlet positioned to deliver liquid to the open end. An exhaust conduit removes liquid from the open end of the housing. The liquid supply conduit can be connectable to a liquid supply for delivering liquid at a first volumetric flow rate to the open end of the housing. A liquid exhaust system can be in fluid connection with the liquid exhaust conduit for removing liquid from the liquid exhaust conduit at a second volumetric flow rate, which exceeds the first volumetric flow rate such that gas with sample is withdrawn with the liquid. The probe can produce a vortex of liquid in the liquid exhaust conduit. A method for sampling a surface and a sampling probe system are also disclosed.

Abstract: A system and method for sampling air at multiple locations in a controlled environment. The system and method includes automatic adjustment of mass flow rates and duration of vacuum connections (either via time elapsed or indirectly by volume) based on rates set by an operator. Additionally, the system and method enables users to monitor and control aspects of the system via network-connected devices. Additionally, the system enable a vacuum pump to be disconnected from power in response to a physical emergency button, a software-based emergency stop button available on network connected devices, and an automatic power disconnection in response to an abnormal mass flow reading that could potentially impact the vacuum pump.

Abstract: An information processing apparatus (2000) acquires time-series data (14) output by a sensor (10) and computes a plurality of feature constants θi and a contribution value ξi representing contribution with respect to the time-series data (14) for each feature constant θi. Thereafter, the information processing apparatus (2000) outputs information in which a set Θ of the feature constants θi and a set Ξ of the contribution values ξi are associated with each other as a feature value of a target gas. As the feature constant θ, a velocity constant β or a time constant τ that is a reciprocal of the velocity constant can be adopted.

Abstract: Various examples are provided related to methane detection in harsh environments. In one example, a method includes drawing a sample of air from at least one first location; delivering the sample to a volume within a sensor block at a second location, where the sensor block includes a gas concentration sensor in communication with the volume; and where a vacuum is applied to the volume within the sensor block to facilitate delivery of the sample to the second location. In another example, a system includes a sampling unit that houses a sensor block, where a sample tube is coupled to an inlet of the sensor block, which includes a gas concentration sensor; an ejector that facilitates delivery of a sample of air from the first location via the sample tube; and a control unit that can receive a gas concentration sensor output from the sampling unit for processing.

Abstract: A system and method for sampling air in a controlled environment that includes two or more air sampling devices at different locations within the controlled environment. A controller is provided at a location outside of the controlled environment and in separate air flow communication with each of the two or more air sampling devices via separate first vacuum tubes, the controller having a manifold configured to separately control a rate of air flow from the two or more air sampling devices to the controller via each of the separate first vacuum tubes and to selectively direct the air flow from each of the separate first vacuum tubes to one or more second vacuum tubes. A vacuum source is provided at a location outside the controlled environment and in air flow communication with the controller via the one or more second vacuum tubes, the vacuum source providing suction and being controlled by the controller to generate the air flow through each of the first vacuum tubes. And, a flow switch for each of the two or more air sampling devices is provided at a location between a corresponding air sampling device and the vacuum source, each of the flow switches being configured to separately measure and control the rate of air flow through a corresponding first vacuum tube. An alarm is automatically activated at a location inside the controlled environment by one or more of the flow switches when the rate of air flow measured at one or more of the flow switches deviates from a desired value by a predetermined amount.
