    摘要： A valve for use with liquid chromatography or other analytical systems may include a separate and removable stator plate. The stator plate may be a with a multi-piece stator plate with different layers. A mounting device mounting device may be adapted to engage the stator plate. The mounting plate may include a plurality of ports for fluidic connections in fluid communication with fluid passageways in the stator plate. Liquid chromatography elements, such as a packed chromatography column, a sample loop, or an electronic device may be formed on one or more layers of the stator plate. A first stator plate may be removed from a valve and replaced by a second stator having additional or different liquid chromatography elements than the first stator plate.
