An air sampling actuator and associated method are disclosed. The air sampling actuator may include a housing configured to mount on a canister, a motor configured to be accommodated in the housing, and an adaptor. The motor may generate a mechanical action, in response to a control signal received by the motor. The adaptor may be coupled to the motor, and configured to interface with a valve-controlling knob of the canister. In a first configuration of the air sampling actuator, the adaptor may be uncoupled from the valve-controlling knob of the canister, and the hook portion may be unengaged with the canister. In a second configuration of the air sampling actuator, the adaptor may be coupled with the valve-controlling knob of the canister, and the hook portion may be engaged with the canister.

A microbial sample collection apparatus includes a double-sided attachment member having opposed attachment surfaces such as adhesive surfaces. A sampling member adheres to one of the opposed surfaces of the double-sided attachment member. A remaining surface of the double-sided attachment member is attachable to a face covering, i.e. face mask, of a test subject. A sample collector adheres the sampling member to a selected location on a face mask interior surface via the double-sided adhesive attachment therebetween. In this manner, microbial samples are cumulatively collected from the exhalation breath path of the test subject wearing the face mask.

A gas analysis system for engaging a sealed container to withdraw and analyze gas from the sealed container, the system comprising: a penetration implement configured to create an opening to permit withdrawal of gas from the container; a chamber operatively coupled to the penetration implement for receiving gas from the container; a gas analyzer; a seal configured to engage the container to enable the system to maintain an enclosed volume comprising the chamber and an interior of the container after the penetration implement has created an opening in the container; and a mechanism to effect flow of gas from the container to the chamber, and thereafter from the chamber to the gas analyzer, the mechanism comprising a first valve operatively coupled to the penetration implement, and a connection pipe configured to connect with the gas analyzer; wherein the first valve is movable between a first position in which it permits flow of gas from the container to the chamber, and prevents gas from escaping from the enclosed volume or being contaminated, and a second position in which it permits flow of gas from the chamber to the connection pipe and the gas analyzer.

The present invention relates to a shale gas extracting device, and provides a shale gas extracting device comprising: a canister, which is vertically and rotatably provided on a canister support vertically provided on both sides of a base, has an receiving space for accommodating a drilled rock sample and a ball mill together in a sealed manner, and has an injection opening at one side of a top thereof; a driving means for vibrating the canister such that the rock sample is crushed by mixing with the ball mill accommodated in the canister; a heating means for heating the canister; and a vacuum pipe, a pressure pipe, a sensor pipe, an injection pipe and an extracting pipe sequentially and detachably coupled to the injection opening of the canister.

In an example, a sample collection apparatus to collect sample from a detection subject includes a circumferential ring tubing surrounding an interior and configured to be moved between bottom ring tubing position and top ring tubing position. The circumferential ring tubing includes air nozzles along a circumferential length of the ring tubing to direct air flow toward the interior as the ring tubing is moved from the top ring tubing position to the bottom ring tubing position, to blow air toward the detection subject in a sample collection zone in the interior and to push a sample of the detection subject via an air flow toward a platform on which the detection subject is positioned. The sample includes particles and/or vapor of the detection subject. A receptacle is disposed below the platform to collect the sample carried by the air flow through collection openings of the platform to the receptacle.

Methods and systems for collecting, transporting and extracting high quality fluid samples for laboratory analyses are disclosed. The systems and methods disclosed are especially important for collecting fluid samples in a manner that most closely resembles the fluids as captured and safely maintains the samples during transportation and extraction at the laboratory.

In an example, a sample collection apparatus to collect sample from a detection subject disposed in a sample collection zone includes a circumferential ring tubing surrounding an interior and configured to be moved between first ring tubing position and second ring tubing position. The circumferential ring tubing includes air nozzles along a circumferential length of the ring tubing to direct targeted air flow within the sample collection zone as the ring tubing is moved between the first ring tubing position and the second ring tubing position, to blow air toward the detection subject in the sample collection zone in the interior and to push a sample of the detection subject via an air flow toward a receptacle. Adjustable actuators are affixed along a periphery of the circumferential ring tubing to adjust the circumferential length of the circumferential ring tubing between a first circumferential length and a second circumferential length.

A flow controller for filling evacuated canisters can be operated at different reference pressures to produce substantially the same flow rates to facilitate inertness testing of the flow controller through demonstrated recovery of trace level chemicals in a challenge standard prior to using the flow controllers to collect air samples for measurement of VOCs during time weighted sampling events. The flow controller can include a first chamber and a second chamber divided by a diaphragm. The first chamber can be fluidly coupled to an inlet of the flow controller and an outlet of the flow controller. The second chamber can be coupled to a reference port of the flow controller. The outlet of the flow controller can be coupled to an initially (e.g., substantially) evacuated canister that can be used to collect a sample of ambient air or challenge standard (e.g., during testing).
