The present invention describes several embodiments of a device that allows for the supporting, storage and deployment of large surface area thin film solid phase microextraction (TF-SPME) chemical samplers from within a sample fluid carrier. The utility of said supporting device originates from the process by which the extraction surface is stabilised within a sample carrying fluid for the extraction of chemical molecules from said sample carrying fluid. The device is also characterized by having a seating cavity, and moving mechanism or cap that can switch the supported TF-SPME chemical sampler between an open, sampling position or closed storage position.

A device for collecting and transferring liquid samples having a detachable sample collecting portion includes an elongated body with a liquid collecting portion disposed at one end and a handling portion disposed at the other end separated by a frangible portion. The sample collecting portion includes an inner surface configured to be wetted by the sample. After collection, the sample is transferred into a separate housing by inserting the sample collecting portion filled with sample into a confining cavity and subsequently breaking the sample transfer device along the frangible portion. The liquid sample is extracted from the collecting portion using known means to drive and control flow in fluidic devices including rotation, capillary pressure or pneumatics. The separate housing may be part of a device capable to process the liquid sample to provide for a system for handling liquid samples.

An electrically passive device and method for in-situ acoustic emission, and/or releasing, sampling and/or measuring of a fluid or various material(s) is provided. The device may provide a robust timing mechanism to release, sample and/or perform measurements on a predefined schedule, and, in various embodiments, emits an acoustic signal sequence(s) that may be used for triangulation of the device position within, for example, a hydrocarbon reservoir or a living body.

Device (1) for surface sampling, comprising: a flat material layer (2) comprising a surface portion (2c) and a circumferential edge portion (2d) defining the boundary of the surface portion (2c), further comprising a sampling volume (2a), wherein the sampling volume (2a) is adapted to comprise a filler device (2b) for filling out the sampling volume (2a), a protective layer (3) arranged on the surface portion (2c) of the material layer (2) by an adhesive (4) arranged on the material layer (2), wherein a portion (3a) of the protective layer (3) extends beyond the boundary of the surface portion (2c) for facilitating a removal of the protective layer (3) from the material layer (2).

Detection and sampling of dissolved hydrocarbons of interest in an environment expected to have hydrocarbon molecules, such as a water column or interstitial water in sediment. An apparatus comprising at least one oleophilic film frame is deployed into the environment and the at least one oleophilic film frame is exposed thereto for a defined period of time, and thereafter isolated from the environment to cease exposure thereto. Hydrocarbon molecules scavenged by the oleophilic film may be analyzed to determine their type and/or concentration.

A sterile sampling apparatus includes a first to seventh flow paths, a sampling section, a first and second pumps, and a first to sixth opening/closing mechanism. The sampling section is disposed in the seventh flow path. The first pump is disposed in the sixth flow path. The second pump is disposed in the seventh flow path. The second flow path includes a first opening/closing mechanism. The third flow path includes a second opening/closing mechanism. The fourth flow path includes a third opening/closing mechanism. The first flow path includes a fourth opening/closing mechanism. The sixth flow path includes a fifth opening/closing mechanism. The seventh flow path includes a sixth opening/closing mechanism. The rate of the second pump is higher than that of the first pump.

An adsorbent, a preparation method therefor and use thereof are provided. The adsorbent has a liquid channel, and the liquid channel has a low-tortuous porous structure. The adsorbent can realize fast and large-scale absorption of various liquids without consuming external energy and not requiring additional apparatuses when in use. The adsorbent can be used for efficient, safe and comfortable medical sampling and can also be used for recovery of various liquids.

The disclosure relates to a sampling system for processing a liquid sample, including a retrieving module configured to be fluidically connected to a liquid-source and configured to retrieve a liquid sample from the liquid-source, a filling module configured to fill the retrieved liquid sample into a sampling container, a storing module configured to store the sampling container filled with the liquid sample, and a disposal module configured to discard the liquid sample.
