Disclosed is a module for sampling from a surface of an industrial vessel without requiring a person to descend into the industrial vessel, using a swab including a stem and a sampling tip, including a swab holder and a conveyor; the swab holder is adapted to receive and secure one end of the swab stem; and the conveyor is configured to set the swab holder in motion on the surface of the vessel.

The present disclosure relates to a specimen collection device comprising ventilation means for drying a collected specimen. The device further comprises a cassette into which the specimen collected is secured to maintain evidentiary chain of custody requirements while providing unobstructed access to a collected specimen for automated analysis. Methods of using the device are also provided.

A device system, and method of use thereof, for collecting, transporting, and processing a biological sample is provided.

Provided herein is a particle analyzer that is operably connected to a probe unit that is capable of both dislodging particles from a surface and sampling the particles after they have been dislodged. The devices and methods described herein may be lightweight and/or handheld, for example, so that they may be used within a cleanroom environment to clean and sample permanent surfaces and tools. The devices may include optical particle counters that use scattered, obscured or emitted light to detect particles, including condensation particle counting systems or split detection optical particle counters to increase the sensitivity of the device and thereby facilitate detection of smaller particles, while avoiding the increased complexity typically required for the detection of nanoscale particles, such as particles less than 100 nm in effective diameter.

The present invention relates to a forensic device suitable for acquisition and storage of biological samples, comprising in an air tight container (1) a water soluble layer (10) which is adhered to a flexible layer (11) by a water impermeable adhesive layer (12), wherein the air tight container (1) comprises a cover (2) defining a storage compartment (3) and a base (4) having attached thereto a protrusion (5) which extends from the base (4) inside said storage compartment (3). Further, the present invention relates to the use of the forensic device to acquire and store a biological sample.

A platform for sampling viral particles on surfaces and porous structures and in the air. The sampling platform includes, for example, a collection pad configured for quantitating viral loads in a fomite or captured form the air. A reservoir or liquid container is associated with the collection pad for interacting a virus collection zone of the collection pad. A liquid medium is disposed within the container. At least one pump is operably configured to move the liquid medium or air through the collection pad for extracting viral particles from the environment.

The invention generally relates to enclosed desorption electrospray ionization probes, systems, and methods. In certain embodiments, the invention provides a source of DESI-active spray, in which a distal portion of the source is enclosed within a transfer member such that the DESI-active spray is produced within the transfer member.

The present disclosure provides for sampling instruments and methods of collecting sample particles. The sampling instrument can include a high-pressure pulsed valve coupled to a gas flow system to displace a sample from a surface. Also included can be a voltage supply coupled to a voltage switch, a suction device, a sample collector, and a collection filter. To collect a sample, extractive particles can be deposited onto a sample present on a substrate. At least a portion of the sample becomes coupled to a portion of the extractive particles to form sample particles. High-pressure gas can be discharged at the sample, thereby aerosolizing a portion of the sample particles to disperse aerosolized sample particles. A portion of the aerosolized sample particles can be collected onto a collection filter to form a collected sample.

Reagents and methods are disclosed for detection of oxidizers and inorganic salts and other analytes of interest. The reagents can interact with their target analytes, especially oxidizer compositions or oxidizer-based explosives, to selectively enhance their ionization yield, interacting by chemical reaction or by forming an associative adduct which facilitates their detection. For example, the reagents can adduct with the counter-ion of the intended analyte for improved direct detection and/or react chemically via acid-base reactions to produce a new product for detection. In another aspect of the invention, reactive reagents and methods are also disclosed that facilitate indirect detection of the analyte at lower temperatures based on reduction-oxidation (redox) chemistry. These reagents are particularly useful in detecting oxidizer analytes.

Assay apparatus for use with a handheld specimen collection tool having an elongated specimen collection tip for bearing bodily specimen therealong. The assay apparatus includes a drum having a transparent, generally cylindrical, hollow drum body with a horizontal longitudinal drum body centerline, an internal drum body surface and an external drum body surface and a backlight illuminator for backlighting the drum body. The assay apparatus includes an elongated specimen collection tube for snug sliding insertion of the elongated specimen collection tip thereinto for depositing bodily specimen on the drum body and an elongated scanner for scanning the backlighted drum body for acquiring a bodily specimen scan.
