    摘要: An apparatus for changing relative concentrations of first and second analyte substances in an analyte sample comprises a sample cell defining a sample chamber therewithin, and a semipermeable boundary member disposed in the sample chamber to define first and second sides of the sample chamber. Sample flow input and sample flow output ducts direct an analyte sample containing respective initial concentrations of the first and second analyte substances into the first side of the sample chamber. The semipermeable boundary member permits diffusion therethrough of the first and second analyte substances to the second side of the sample chamber at different rates. An analyte sample in the second side of the sample chamber, and an analyte sample exiting the first side via the sample flow output duct, have respective concentrations of the first and second analyte substances that are different from the initial concentrations.

    摘要: Methods and sub-systems for substantially optimizing the absorbance measurement in optical instruments are provided. A method comprises forming a liquid sample into a droplet extending between two opposing surfaces, passing a light beam through the sample, and varying the distance between the two opposing surfaces until a distance substantially corresponding to a optimum absorbance is obtained.

    摘要: Aspects of the invention include plasma generating devices and systems thereof, as well as methods of using the same in plasma generation. Embodiments of the plasma generating devices include a resonator having a discharge gap and a ground plane disposed on opposing sides of a substrate; and a gas flow element configured to flow gas through the discharge gap. In using the plasma generating devices, a gas is flowed through the discharge gap and sufficient power is applied to the resonator to produce a plasma, e.g., in the form of a plasma jet, at the discharge gap. The subject devices and methods find use in a variety of different applications.

    摘要: The present invention includes a heat sealable capsule adapted for use in analysis devices such as GCs, and methods for using the capsules to perform analysis in such devices. The capsules include a tube having an end that is heat-sealed to contain a sample that is to be analyzed at an injection temperature. The tube includes a heat sealable medium having a heat seal that closes the end, the tube having an inner and outer surface, both of the surfaces being substantially chemically inert with respect to the sample. The tube is substantially free of any material that outgases at the injection temperature. The tube is openable without breaking into pieces, and remains intact at the injection temperature. The capsule can include a programmable tag that stores information related to the sample contained therein.
