摘要： This invention relates to a sampling device. The device includes an elongate separating member having a sampling side and a non-sampling side. One or more through openings extend from the sampling side to the non-sampling side of the elongate member. The separating member is adapted for insertion into a reservoir of particulate material so as to define a sampling zone and a non-sampling zone within the reservoir. A shaft is positioned away from the sampling side and operably associated with the separating member, wherein the shaft is selectively rotatable about its longitudinal axis. One or more sample capturing scoops are attached to the shaft so as to be aligned with a respective opening. The or each scoop has a leading edge, a trailing edge and a cavity for receiving a sample of particulate material. The device is configured such that rotation of the shaft about its longitudinal axis causes a corresponding rotation of the or each scoop between a first position and a second position. In the first position, the leading edge of the associated scoop is located within the respective opening such that the opening is effectively closed and the remainder of the scoop projects away from the sampling side such that the sampling side of the separating member is free of protuberances during insertion into the reservoir. In the second position, the scoop is positioned on the sampling side and the leading edge of the associated scoop bears against the sampling side of the elongate member, thereby to enclose the sample of particulate material by the rotation of the scoop towards the second position.

摘要： A field apparatus (also referred to as a “biosampler”) is configured to automatically capture multiple samples of an aqueous medium (for example, water from a lake) and process same to preserve unstable analytes in the field. In this way, a set of samples from the aqueous medium can, for example, be captured at multiple points in time, processed with a biopreservative to preserve unstable analytes (for example, RNA) and then later collected for further analysis. Alternatively, multiple samples of the aqueous medium can be collected and preserved at one moment.

摘要： A method of particle detection in an aspirated particle detection system having a sampling pipe network and a particle detector. The method includes drawing sample air to the particle detector through the air sampling network; analyzing the sample air with the particle detector; entering an amplification phase, in the event that a concentration of particles in the sample air greater than a predetermined threshold is detected, to create a plurality of sample air packets in the sampling pipe, wherein each sample air packet corresponds to a sampling inlet and includes an amplified concentration of air drawn from the corresponding sampling inlet; transporting the sample air including the plurality of sample air packets through the sampling pipe to the particle detector; and determining through which sampling inlet any particles entered the particle detection system.

摘要： Contaminant mass collection in saturated sedimentary environments for bioavailability determination. A casing includes a screen between the environment that is subject to sampling, such as a saturated sediment and the device itself. The casing includes a water intake zone, a pump, and sorptive media. The water intake zone, the pump, the screen and the sorptive media, are all operably linked in sequence. The screened casing is secured to form an in situ device; the screen is in fluid communication with the water intake zone and excludes endemic sediments and aquatic life. The in situ device is deployed in the saturated sedimentary environment. The pump operates to concentrate analytes from the selected environment in the sorptive media, where the concentrated analytes include the analyte mass of time-weighted fluid samples.

摘要： A sniffing leak detector which comprises a first suction line in a sniffing probe, the line leading to a main device, is provided with a larger second suction line through which gas is sucked in from the sniffing tip by a gas delivery pump. By connecting the second suction line, the distance sensitivity is increased. By disconnecting the second suction line, on the other hand, the sensitivity is increased. Thus, it is possible to first search for leaks by use of a high gas throughput and subsequently exactly determine the leaks under the quantitative aspect by use of a reduced flow.
