A method for determining a radionuclide concentration of a material is provided. The method comprises placing a detector in a protective structure, wherein the detector is coupled to a single-channel analyzer. The method further comprises inserting the protective structure in a material, wherein the material comprises a radionuclide. The method additionally comprises measuring the moisture content of the material to be analyzed.

The analyzer of the present invention is specifically adapted to provide moisture determinations for foods and other agricultural material. It allows the operator to introduce a precise weight of sample into a crucible in a closed furnace in a controlled environment through an access port in the furnace cover. The access port in the cover can be tapered to allow easy access to an underlying aligned crucible and allow an operator to add and remove sample material from the crucible until a precise desired sample weight is reached as measured by a balance within the furnace. The access port is enclosed by an insulated cover after the samples are sequentially placed in the crucibles.

The method comprises placing the material to be analyzed into a vessel, wherein the material comprises a radionuclide, wherein the material has a known volume, and wherein the vessel has a fixed geometry. The method further comprises weighing the material to be analyzed and measuring the moisture content of the material to be analyzed. The method additionally comprises placing a protective structure in the material and placing a detector in the protective structure, wherein the detector is coupled to a single-channel analyzer. The method also comprises counting the emitted radiation having a known energy over an interval of time to produce a count per time, wherein the emitted radiation is emitted from the radionuclide and then dividing the count per time by the weight of the material to produce a count per time per weight.

An apparatus for determining the amount of water in a liquid condensate. The apparatus comprises a vessel for containing a stream of liquid condensate. A first section of the vessel comprises an inlet for receiving the stream of liquid condensate and a second section of the vessel comprises an outlet for outputting the stream of liquid condensate. The inlet is configured to be removably coupled to an input feed line and the outlet is configured to be removably coupled to an output feed line. The apparatus further comprises an adsorbent material disposed in the vessel for removing water from the liquid condensate and a cap configured to be removably coupled to an opening in the vessel to thereby allow the adsorbent to be removed from the vessel.

A moisture measuring device for gases, in particular compressed gases, compressed air and the like, for moisture content detection in a gas supply system, includes a gas sampling input for the test gas which is connected to the gas supply system. A separate gas channel used only for the moisture measurement branches off from the gas sampling input. The separate gas channel is connected with a measuring cell in which a dew point sensor is arranged. A drying cell with a drying agent is connected downstream of the measuring cell. The drying cell is substantially hermetically sealed against the outside environment. Lastly, the output side of the drying cell is connected to an outlet channel leading to the outside environment. A gas supply system may have the form of a compressed gas system, a compressor station, a storage system and the like.

A gas analyzing method includes obtaining, dividing, selecting, extracting, and analyzing. In the obtaining, signal is obtained from a sensor exposed to sample gas under a condition where molecules contained in the sample gas is more readily adsorbed to the sensor in a second period than in a first period and a third period in a measurement period for the exposure. In the dividing, each of the second and third periods is divided into divided sections. In the selecting, an extraction section is selected from a part of the divided sections. In the extracting, feature of the signal in the extraction section is extracted. In the analyzing, analysis on the molecules contained in the sample gas is performed based on the extracted feature among features of the signal in the measurement period, and a result of the analysis is outputted.

An absorbent article, including a liquid permeable top sheet, a pulpless absorbent core, the core including synthetic fibers and a super absorbent material, the super absorbent material being settled and stabilized by an open formation bottom high loft layer with fibers oriented in a Z direction, and a liquid impermeable backsheet, wherein the absorbent core is positioned between the top sheet and the backsheet.

The invention relates to a gas sensor for detecting one or a plurality of volatile compounds in a gas, the sensor comprising: a signal transducer comprising a layer comprising nanopores wherein the gas has access to the nanopores in said layer, a heating or cooling element, with adjustable temperature settings, for heating or cooling said layer comprising said nanopores, means for access of said gas to said layer comprising said nanopores, an electronic circuit, monitoring a time-dependent and a temperature-dependent signal generated by the signal transducer upon adsorption or release of a compound from the nanopores in said layer.

An uptake measurement system for determining analyte uptake in a material is described. The uptake measurement system includes a test chamber where an uptake sensor measures the uptake of one or more gases under testing conditions. The uptake sensor includes at least two transducers, each measuring distinct characteristics of the analyte as it is adsorbed or absorbed onto the material. Based on the measurements from both transducers and the testing conditions, the uptake of the gas by the material is calculated.

A method including receiving a specimen comprising a carrier, a first target species, and a first component and storing at least a portion of the carrier and the first target species in a storage media by self-driven filtering of the specimen in the storage media, wherein the storage media comprises porous superabsorbent polymer (PSAP) beads. The PSAP beads provide for fast and self-driven microfiltration of biofluid samples. The treatment effectively separates small analytical targets (e.g., glucose, catalase, and bacteriophage) and large undesired components (e.g., bacteria and blood cells) in the biofluids by capturing the former inside and excluding the latter outside the PSAP beads. The treatment can reduce sample volume, self-aliquot the liquid sample, avoid microbial contamination, separate plasma from blood cells, stabilize target species inside the beads, and enable long-term storage at room temperature.
