    摘要： 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conduit at a second volumetric flow rate, which exceeds the first volumetric flow rate such that gas with sample is withdrawn with the liquid.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.

    摘要： A system for collecting particles having a suctioning device and a chamber for centrifugating and collecting particles. The centrifugation chamber having a guiding edge as well as an air inlet and an air outlet. The device having an assembly including an air suctioning conduit, a member including a guiding and receiving system, at least one guiding edge of the chamber, the member being mobile relative to the conduit between a first position, wherein the at least one guiding edge can be guided and received in the guiding and receiving system and a second position for collecting particles, where the air outlet of the chamber is applied on an end of the conduit.

    摘要： 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.

    摘要： A sampling system is disclosed which comprises a collection chamber equipped with an inlet and first and second outlets; a pump which creates a flow of fluid into said inlet from the ambient environment, wherein said collection chamber divides the flow of fluid into a first major flow of fluid along which flows along a first flow path between said inlet and said first outlet, and a second minor flow of fluid which flows along a second flow path between said inlet and said second outlet; a collection surface disposed within said collection chamber and within the second flow path such that particles in the flow of fluid into said inlet impinge on said collection surface; a heater which vaporizes particles that collect on said collection surface; and an analyzer which analyzes the composition of the fluidic flow through said second outlet.
