    摘要： An apparatus for suppressing an eluent of an aqueous sample stream including analyte ions of one charge, positive or negative, comprises a primary channel member, a first block, a first regenerant flow channel, a first charged barrier, a second block, a second regenerant flow channel, a second charged barrier, a first stationary flow-through ion exchange material, and optionally a first electrode and a second electrode. The first stationary flow-through ion exchange material comprises a polyolefin substrate having a functional polymer layer disposed thereon. The polyolefin substrate has a pore structure with a pore size ranging from about 5 microns to about 250 microns. The functional polymer layer has a thickness ranging from about 1 micron to about 20 microns, and a layer pore structure having a pore size ranging from about 1 nm to about 100 nm. The functional polymer layer comprises an ion exchange layer.

    摘要： A method and apparatus are disclosed for determining the concentration of individual components within a fluid mixture by determining the permittivity of the individual components. The method and apparatus use a reference sensor and at least one measurement sensor positioned inside the same sensor device that is immersed in the fluid mixture to be measured. Signals, such as radio frequency or microwave, are sequentially transmitted at multiple, known, constant frequencies to and reflected from both the reference and measurement sensor(s). Permittivities of the individual components are determined from these transmitted and reflected signals and information about the concentration of the individual fluids and other compounds within the fluid mixture and the density of the fluid mixture are produced. Repetitive sampling and processing of these signals allow determination and real-time monitoring of the concentration of individual components within a mixture of fluids. The present invention provides self-calibration, accurate frequency maintenance and self-selection of an operating frequency range.

    摘要： A two-dimensional fluorescent densitometry for measuring a specimen plate having a specimen spot such as phospholipide two-dimensionally developed and fluorescent-labelled on a TLC plate. The densitometer comprises an excitation optical system for scanning a measuring plate with an excitation light beam, a fluorescence detection system for detecting a fluorescence from the measuring plate, a correction table for storing fluorescent data together with positional information in a scanning direction on the measuring plate, and an arithmetic section for dividing fluorescence detection data by fluorescent data at the same position in the scanning direction on the measuring plate stored in the correction table.
