    摘要: A small liquid sample (24) to be tested is contained within an annulus (18) on the upper surface (14) of a substrate (12). In one embodiment, a reagent diffuses into the sample through a membrane (28) in a junction hole (26), the junction hole connecting upper (14) and lower (16) surfaces of the substrate. Optical measuring equipment (70, 72) detects a measurable change in an optical property of the sample. In an alternate embodiment, a flow of gas (30), directed at the small liquid sample (24), causes the sample to flow in a controlled manner over the surface of an electrode (20), disposed on the substrate surface (14). In another alternate embodiment, a special averaging electrode (20) is disposed in a non-homogeneous sample (24). Highly reproducible and accurate hydrodynamic electrochemical studies and analyses of microliter size samples are thus achievable, without the need for moving mechanical parts.

    摘要: An automatic chemical analyzer in which a reaction solution is stirred by air ejected from an air ejection hole placed above a reaction container. The reaction region can be washed and cleaned sufficiently without causing damage, such as exfoliation of a coating reagent. A reaction container disk is provided with a pore and a pressure detector connected with the pore. Before and after the stirring operation, the ejection hole (nozzle) ejecting air is moved and the output value of the pressure detector is compared with a previously measured normal value. With a discharge pipe and a suction pipe inserted to the opening of the reaction container to be close to both ends of the opening and the side wall of the container, the reaction region at the bottom of the container is washed by continuous discharge and suction of cleaning fluid.

    摘要: An automatic chemical analyzer in which a reaction solution is stirred by air ejected from an air ejection hole placed above a reaction container. The reaction region can be washed and cleaned sufficiently without causing damage, such as exfoliation of a coating reagent. A reaction container disk 161 is provided with a pore 240 and a pressure detector 241 connected with the pore. Before and after the stirring operation, the ejection hole (nozzle) 170 ejecting air is moved and the output value of the pressure detector is compared with a previously measured normal value. With a discharge pipe 1101 and a suction pipe 1102 inserted to the opening of the reaction container 1140 to be close to both ends of the opening and the side wall of the container, the reaction region 1150 at the bottom of the container is washed by continuous discharge and suction of cleaning fluid.

    摘要: Methods and systems for enhancing fluidization of nanoparticle and/or nanoagglomerates are provided. A fluidization chamber is provided with a fluidizing medium directed in a first fluidizing direction, e.g., upward into and through a bed containing a volume of nanoparticles and/or nanopowders. A second source of air/gas flow is provided with respect to the fluidization chamber, the secondary air/gas flow generally being oppositely directed relative to the fluidizing medium. Turbulence created by the secondary gas flow is advantageously effective to aerate the agglomerates and the shear generated by the jet is advantageously effective to break apart nanoagglomerates and/or reduce the tendency for nanoagglomerates to form or reform. A downwardly directed source of secondary gas flow located near the main gas distributor leads to full fluidization of the entire amount of powder in the column. The oppositely directed fluid flow facilitates powder circulation within the fluidization chamber, thereby enhancing fluidization results.

    摘要: Methods and systems for enhancing fluidization of nanoparticle and/or nanoagglomerates are provided. A fluidization chamber is provided with a fluidizing medium (e.g., a fluidizing gas) directed in a first fluidizing direction, e.g., upward into and through a bed containing a volume of nanoparticles and/or nanopowders. A second source of air/gas flow is provided with respect to the fluidization chamber, the secondary air/gas flow generally being oppositely (or substantially oppositely) directed relative to the fluidizing medium. Turbulence created by the secondary gas flow, e.g., a jet from a micro-jet nozzle, is advantageously effective to aerate the agglomerates and the shear generated by the jet is advantageously effective to break apart nanoagglomerates and/or reduce the tendency for nanoagglomerates to form or reform. A downwardly directed source of secondary gas flow located near the main gas distributor leads to full fluidization of the entire amount of powder in the column. In addition, the oppositely directed fluid flow facilitates powder circulation within the fluidization chamber, thereby enhancing fluidization results. Use of oppositely directed fluid flow is believed to transition a bed that is exhibiting agglomerate bubbling fluidization (ABF) behavior into a bed that exhibits agglomerate particulate fluidization (APF) behavior
