    • Embodiments of the present invention feature a method and device for controlling the flow of fluid. One embodiment of the device for controlling the flow of fluid comprises a rotor, stator and compression means. The rotor has a rotor fluid communication means and at least one rotor load bearing surface. The rotor load bearing surface sealably engages a stationary load bearing surface. The rotor is capable of assuming a first position and a second position by rotation. The stator has a stationary load bearing surface having stator fluid communication means. The stationary load bearing surface sealably engages the rotor load bearing surface and permits rotation of the rotor with respect to the stator. At least one of the rotor bearing surface and said stator load bearing surface has a diamond-like carbon-silica coating.

    • Disclosed is a chromatographic system and method which includes a passive pre-heater assembly. In the inventive system and method a fluid mixture is supplied from an injector to the pre-heater assembly and then to a chromatographic column having an active heating source. The pre-heater assembly includes a convoluted tube with first and second ends and a fluid passage extending centrally therebetween, first and second end fittings attached respectively to the first and second ends of the convoluted tube, and a thermally conductive film attached to an outer surface of the convoluted tube. The first end fitting is adapted for fluidly connecting the first end of the convoluted tube to the injector and the second end fitting is adapted for fluidly connecting the second end of the convoluted tube to the chromatographic column. The thermally conductive film conveys heat from an active heating source of a chromatographic column to the convoluted tube when the pre-heater assembly is positioned adjacent to the active heating source. The central fluid passage in the convoluted tube has a series of bends which function to create a secondary fluid flow field that is substantially orthogonal to a primary flow field established when fluid is traversing the fluid passage in the tube.
    • 公开了一种包括无源预热器组件的色谱系统和方法。 在本发明的系统和方法中,将流体混合物从注射器供应到预热器组件,然后到具有主动加热源的色谱柱。 预热器组件包括具有第一和第二端的回旋管和在其间中间延伸的流体通道,分别连接到回旋管的第一和第二端的第一和第二端配件以及附接到外表面的导热膜 的回旋管。 第一端配件适于将回旋管的第一端流体连接到注射器,并且第二端配件适于将回旋管的第二端流体连接到色谱柱。 当预热器组件邻近主动加热源定位时,导热膜将热量从色谱柱的活性加热源传送到回旋管。 回旋管中的中心流体通道具有一系列弯曲,其功能是产生与流体横穿管中的流体通道所建立的主流场大致正交的次级流体流场。
