Abstract: Sampling devices for sampling an aqueous source (e.g., field testing of ground water) for multiple different analytes are described. Devices include a solid phase extraction component for retention of a wide variety of targeted analytes. Devices include analyte derivatization capability for improved extraction of targeted analytes. Thus, a single device can be utilized to examine a sample source for a wide variety of analytes. Devices also include an isotope dilution capability that can prevent error introduction to the sample analysis and can correct for sample loss and degradation from the point of sampling until analysis as well as correction for incomplete or poor derivatization reactions. The devices can be field-deployable and rechargeable.

Abstract: A pressure cell for sum frequency generation spectroscopy includes: a metal pressure chamber; a heating stage that heats the liquid sample; a pump, connected to an interior of the metal pressure chamber, that pressurizes the interior of the metal pressure chamber; and a controller that controls the pump and the heating stage to control a pressure of the interior of the metal pressure chamber and a temperature of a liquid sample. The metal pressure chamber includes: a base that retains the liquid sample; a removable lid that seals against the base to enclose the liquid sample in the metal pressure chamber; and a window in the removable lid that exposes the liquid sample to an exterior of the metal pressure chamber.

Abstract: A water quality monitoring system is disclosed including a sampling pipe that acquires steam that passes a bleed pipe that bleeds steam from a low pressure turbine to which steam of low pressure is supplied from among steam turbines, a steam inlet tank into which the steam acquired by the sampling pipe flows, a water quality measurement apparatus that measures the water quality of condensed water condensed from the steam flowed in the steam inlet tank, and a water quality diagnosis apparatus that diagnoses the water quality of the condensed water using a result of the measurement of the water quality measurement apparatus. The steam inlet tank is installed at a location higher than that of the water quality measurement apparatus such that the water quality measurement apparatus measures the water quality of the condensed water boosted to the atmospheric pressure utilizing the head difference.

Abstract: Highly efficient and rapid filtration-based concentration devices, systems and methods are disclosed with sample fluidic lines and a filter packaged in a disposable tip which concentrate biological particles that are suspended in liquid from a dilute feed suspension. A sample concentrate or retentate suspension is retained while eliminating the separated fluid in a separate flow stream. The concentrate is then dispensed from the disposable tip in a set volume of elution fluid. Suspended biological particles include such materials as proteins/toxins, viruses, DNA, and/or bacteria in the size range of approximately 0.001 micron to 20 microns diameter. Concentration of these particles is advantageous for detection of target particles in a dilute suspension, because concentrating them into a small volume makes them easier to detect. A single-use pipette tip includes fluid ports for aspirating the sample and connecting to a concentrating unit.

Abstract: A system includes an analysis system at a first location and one or more remote sampling systems at a second location remote from the first location. A sampling system can be configured to receive a remote liquid sample. The system also includes a sample transfer line configured to transport gas from the second location to the first location. The sample transfer line is configured to selectively couple with a remote sampling system for supplying a continuous liquid sample segment to the sample transfer line. The system can further include a sample receiving line at the first location. The sample receiving line is configured to selectively couple with the sample transfer line and the analysis system to receive the continuous liquid sample segment and supply the sample to an analysis device.

Abstract: A field-flow fractionation device includes a separation channel, a carrier fluid supplier, a separation membrane, a waste liquid chamber, a cross-flow flow rate adjuster, and a carrier fluid adder. The carrier fluid adder is configured to add, to a flow of a carrier fluid having passed through the separation membrane, a flow of another carrier fluid at a carrier fluid adding position set on an upstream side of the cross-flow flow rate adjuster so that the flow rate of the carrier fluid flowing into the cross-flow flow rate adjuster is larger than the flow rate of the carrier fluid having passed through the separation membrane.

Abstract: [Problem to be solved] To provide a sample storage tube wherein a lid is a push stopper lid type securing the area for writing two-dimensional code.
[Solution] A sample storage tube 100 comprise a tube body 120 for storing a sample; a push stopper lid body 110 for capping the upper opening 121 of the tube body 120; and a hinge body 130 for connecting the tube body 120 and the push stopper lid body 110. The push stopper lid body 110 and the tube body 120 and the hinge body 130 are molded in one piece, wherein a part of them is formed by the light transmissive material and the other part of them is formed by the opaque material in which the information code can be written. The information writable areas are installed at least on the upper surface of the push stopper lid body 110 and the bottom surface 123 of the tube body 120. The information code can be written on both the upper surface of the push stopper lid body 110 and the bottom surface 123 of the tube body 120. The opaque material extends continuously from the upper surface of the push stopper lid body 110 to hinge body 130 and the side surface of the tube body 120 up to the bottom surface 123 of the tube body 120 as one piece.

Abstract: A well sampling apparatus is described herein. The well sampling apparatus includes one or more pressure-activated samplers in a sampling assembly. The samplers are coupled to an activating mechanism that includes a remotely activated local actuator. The remotely activated local actuator is coupled to a pressure source that, when released by the remotely activated local actuator, operates the pressure-activated sample to obtain a sample fluid.
