Abstract: A novel gas injection valve for injecting discrete charges of gas into a mobile phase or carrier stream is provided. Injection valves of the invention comprise a plurality of microvalves capable of receiving gas at different pressures and emitting discrete charges of gas at approximately the same pressure. The invention further provides for parallel injection valve arrays capable of injecting multiple samples substantially simultaneously and a method of injecting discrete gas samples at a controlled pressure to a high-resolution gas chromatograph.

Abstract: Method for preparing a mixed powder sample by mixing two or more different powders comprising transferring a quantity of a first powder to a mixing vessel and transferring a quantity of a second powder to the mixing vessel to form a powder bed in the mixing vessel comprising the first and second powders. The quantities of the powders are selected so the mixed sample has a predetermined ratio of first powder to second powder. The powder bed is fluidized to mix the powders and produce a mixed sample. The mixed sample weighs about 5 grams or less. The invention also includes apparatus for preparing mixed powder samples by mixing two or more different powders.
