The invention relates to a method for the determination of analyte concentrations in liquid and/or gaseous media, whereby several probes withdraw at least one analyte from several sampling regions (3), across a semi-permeable membrane (2), by time-controlled diffusion of the at least one analyte between the relevant medium and a diffusion medium, which is fed to the sampling regions (3) through fluid lines (5a, 5b), by means of at least one pump (6). The diffusion medium is removed from the sampling region, with concomitant introduction of new diffusion medium and led to at least one detector (7) and analysed by the same. Said pump (6) works continuously and the diffusion medium may be alternately pumped to the fluid line sections (5b), by means of a multiple valve arrangement or a multiway-valve (12), arranged in series with the sampling regions (3).

Automatic sampler for liquids

Номер: DE0003428213A1
Принадлежит:

Automatic sampler for liquids for simplifying the taking of samples, especially from stretches of water and/or tanks with given sample criteria, such as, for example, filling level, amount of water, turbidity, liquid level, conductivity etc., especially for taking single samples. In this sampler, the sample liquid is drawn in through one or more suction lines as a result of a vacuum set up in the sample container. The suction lines are provided with clamp valves which are actuated by an electronic unit. In order to facilitate operation, the sampler is provided with interchangeable sample units which may be interchanged even as operation proceeds. Particularly with a view to using the sampler outdoors, it is independent of mains supply. The shockproof and shake-proof design of the clamp valves largely precludes incorrect taking of samples, and makes it possible to set up the sample containers in the laboratory.

    This disclosure relates methods and systems for obtaining a sample of a liquid or gas phase from a multiphase mixture flowing in a pipeline, where the multiphase mixture comprises oil and/or a gaseous hydrocarbon and the pipeline is configured for the transport of the oil and/or gaseous hydrocarbon. The sampling system comprises means for causing outward flow i.e away from a centre axis of the pipeline towards an inner surface of the pipeline. This may be an expansion chamber 30 or a restrictor (Figure 1C) Expansion causes the liquid phase to become dispersed onto the inner surface 40 of the expansion chamber such that it can be collected in sample collector 50. Gas may be collected separately. After obtaining the sample of the liquid or gas phase of the multiphase mixture, sensing devices, meters, sensor systems or the like may be used to analyze the properties of the collected samples.

    A single phase sampling apparatus and method for retrieving a formation fluid sample at or above the bubble point of the sample. The apparatus utilizes a gas charge contained between a sample piston (1) and a charging piston (3) to maintain a formation sample at the desired pressure. The charging piston utilizes the hydrostatic pressure present at the depth of the desired formation sample to compress and therefore increase the gas charge to the appropriate pressure necessary to maintain the formation sample at the desired pressure. The utilization of hydrostatic pressure to increase the pressure of the gas charge allows the use of a low pressure gas charging system to prepare the apparatus prior to sampling, thereby increasing the safety and ease of use of the device.

    Принадлежит:

    Active biofluid management may be advantageous to the realization of wearable bioanalytical platforms that can autonomously provide frequent, real-time, and accurate measures of biomarkers in epidermally-retrievable biofluids (e.g., sweat). Accordingly, exemplary implementations include a programmable epidermal microfluidic valving system capable of biofluid sampling, routing, and compartmentalization for biomarker analysis. An exemplary system includes a network of individually-addressable microheater-controlled thermo-responsive hydrogel valves, augmented with a pressure regulation mechanism to accommodate pressure built-up, when interfacing sweat glands. The active biofluid control achieved by this system may be harnessed to create unprecedented wearable bioanalytical capabilities at both the sensor level (decoupling the confounding influence of flow rate variability on sensor response) and the system level (facilitating context-based sensor selection/protection). Through integration with a wireless flexible printed circuit board and seamless bilateral communication with consumer electronics (e.g., smartwatch), contextually-relevant (scheduled/on-demand) on-body biomarker data acquisition/display may be achieved.
