摘要： A titration apparatus includes a titration measuring cell with a titration vessel, a valve device, and a first pump for sucking liquid through a first fluid line into a temporary storage container and transporting it via a second fluid line into the titration vessel. The temporary storage container is arranged in a fluid path between the first pump and the valve device. A third fluid line connects the first pump to the temporary storage container and is filled with a working liquid that does not affect the titration. A second pump conveys a volumetric solution into the titration vessel. An electronic controller controls the first and the second pumps and the valve device to convey a liquid from the first liquid supply into the temporary storage container to transport the liquid into the titration vessel and transport the volumetric solution into the titration vessel to carry out titration.

摘要： A fluid sampling device having a first conduit configured to couple an outlet of a fluid source to a sample inlet port; a second conduit configured to couple a sample outlet port to an inlet of the fluid source; an expansion chamber including an inlet and an outlet coupled to the first and second conduits by a valve assembly; and a pressure relief valve configured to couple the outlet of the expansion chamber to the inlet of the fluid source. The fluid sampling device facilitates acquisition of a fluid sample and subsequent purging of its internal components while inhibiting the release of sample fluid to the surrounding environment, thereby protecting the environment and sampling personnel from harmful chemical release. The fluid sampling device may facilitate a sample acquisition process that provides closed-loop flush and expansion operations for obtaining a representative sample at the appropriate fill density of the sample vessel.

摘要： Improvements in a variable volume capture device are disclosed to capture a variable amount of sample. The variable amount is controlled by a linear actuator that produces a variable and adjustable stroke length that capture the programmed amount of fluid in the syringe barrel. Air or other supernatant fluid can be separated and expelled at this point. The captured fluid is then dispensed out of the syringe barrel for further testing and analysis. The capture device is then able to drain or flush the sample. Valves located on each side of the syringe barrel allow for sample collecting, dispensing and draining to ensure that the capture device is free to collect new samples. The variable volume capture device can have changeable syringe and barrel diameters and lengths to accommodate larger or smaller ranges of samples.

摘要： An apparatus for taking a sample from at least one fluid system and for passing the sample to an analytical evaluation system connects the piston rod of the sample-taking piston with a controllable drive. A flushing gas feed opens into a feed line downstream from a three-way valve, via a shut-off valve. The three-way valve, the controllable drive, and the shut-off valve are coupled with one another so that for taking a sample, the three-way valve releases the path of the sampling line to the sample-taking cylinder, the shut-off valve is open, and the controllable drive withdraws the sample-taking piston from the sample-taking cylinder, and, for applying the sample to the evaluation system, the shut-off valve is closed, the three-way valve is switched to release the path from the sample-taking piston to the feed line, and the controllable drive pushes the sample-taking piston completely back into the sample-taking cylinder.

摘要： An in situ autosampling method and associated sampling device for capturing a material sample from a vessel. Methods of the present invention make use of a sampling device having an extendable sample capture element with a concave sample capture pocket located near a distal end thereof. The sample capture pocket is adapted to capture a known volume of material when the sample capture element is extended into said material. The material sample remains trapped in the sample capture pocket upon sample capture element retraction. Ports in the sample capture pocket may be placed in communication with corresponding material transfer channels extending through the sample capture element to allow for the in situ processing of a material sample, and the subsequent discharge of the sample to an analyzer or another downstream location.
