摘要： A liquid chromatographic instrument includes specimen vessels in randomly designated locations. An automatic sampler sequentially samples specimens from selected vessels based on instructions from a set of command instruction lines. A detector module measures characteristics of each sampled specimen, and results for each test specimen relative to a standard specimen are computed. A command sequence program includes reading of a user inputed ordered list to effect a sequential selection of each location designation according to the ordered list, generation of a command instruction line corresponding to each sequential selection and containing a location designation and measurement instructions for each selected specimen, counting of the number of command instruction lines generated since a nearest prior calibration command instruction line, and in response to the counting number being equal to the calibration frequency, generation of a next calibration command instruction line containing the location designation and the measurement instructions for the standard specimen.

摘要： The invention comprises methods and apparatus for the mass spectrometric determination of the isotopic composition of an element comprised in an analysis gas (that is, a gas comprising the element in elemental form or in the form of a simple compound, e.g., nitrogen or carbon dioxide). First and second flows of a carrier gas (e.g., helium) are simultaneously passed into the mass spectrometer, and samples of analysis gas and a reference gas are respectively introduced into the first and second flows during selected time intervals. The time intervals are selected so that mass spectrometric measurements are made on the analysis gas samples in the absence of any signal from the reference gas samples, and v.v. A preferred embodiment comprises a gas chroatograph through which a sample containing the element is passed, and conversion means to convert the eluting sample into the analysis gas.

摘要： A liquid sample to be analyzed is subjected to a vaporizing step. The vaporized components are submitted to a first separation stage by introducing said components into a packed chromatography column and flowing carrier gas through said column. The effluent of the first stage is passed through a flow dividing chamber. A second separation stage is performed by passing the effluent of the flow dividing chamber to a capillary chromatography column and flowing carrier gas therethrough. After a predetermined period of time, flushing gas is introduced through the flow dividing chamber and flowed through the first-stage packed column in a direction opposite to the original direction of flow while the direction of flow remains unchanged in the capillary column.

摘要： The molecular weight and molecular weight distribution of diverse ultra-high molecular weight water soluble polymers is rapidly determined based on apparent size by passage of extremely dilute samples of the polymer (1-250 ppm) through a column of nonporous packing whereby separation into molecular weight (apparent size) fractions is obtained predominantly based on flow (i.e., hydrodynamic chromatography). Detection of the extremely dilute sample polymer is accomplished, e.g., by tagging the polymer with a fluorescent agent and using a flow-through fluorometer detector. The molecular weight characterization of the polymers is determined independent or less dependent of the composition of the polymer by analyzing the sample in its nonionized form.

摘要： Proposed is a device for radiochromatographic analysis of mixtures of substances containing components tagged by radioactive isotopes, such as soft .beta.-isotopes comprising a chromatographic column, a detector of nuclear radiation and a chromatographic detector connected in series along the flow of the substance being analyzed. The detector of nuclear radiation is provided with a cell made as a tube with a scintillator applied onto its inner surface in the form of a solid layer. The tube is provided with movable means for sequentialy cooling and heating the same and a light detector which is movable along the length of the tube. In operation, upon introduction of the portion of the mixture being analyzed into the column, with the heater interacting with the tube, the heater and cooler are moved so that by the time the last component of the mixture exits from the column, the cooler is in interacting relationship with the tube whereby the components of the mixture are frozen. According to one mode of operation, the light detector is then moved to register the glow of the strips of the radioactive components whereby a radiochromatogram can be derived.

摘要： A method and apparatus is disclosed for correcting errors in a chromatographic analysis caused by changes in ambient atmospheric pressure. The output signal from a chromatograph is summed with the output signal from a pressure transducer. The output signal from the pressure transducer varies with changes in the atmospheric pressure from a reference pressure and is calibrated in such a manner as to provide a corrected chromatographic analyzer output signal when it is summed with the output signal from the chromatograph. In this manner pressure compensation is provided where normalization of the chromatographic analyzer output signal is not possible or is undesirable.
