Abstract: An arrangement for metering a gaseous sample in a carrier gas stream has a sample gas path and a carrier gas path, both paths being connected to a carrier gas source. By introducing different pressures into the sample gas path and the carrier gas path, a metered amount is extracted from a sample slug and diverted into the carrier gas stream via a connection gas path through the carrier gas path. The sample gas path has two flow resistances in front of and behind a branch point of a connection gas path. One resistance lies between the carrier gas source and a metering unit and a gas volume of the sample gas path between the branch point of the connection gas path and the other flow resistance is dimensioned such that the sample slug only reaches the second resistance after extraction and diversion of the metered amount.

Abstract: Integrated system for the concurrent quantitative analysis, using ion exchange resin, of chromatographically separable cations and anions contained in a single measured portion of aqueous sample solution includes an eluant water reservoir, a sample injection valve, a pump delivering water from the reservoir to the sample injection valve, and thence to a first stream splitter feeding two parallel ion exchange columns. One column is charged with anion exchange resin and the other with cation exchange resin, preferably with differing bed depths but in any event selected in nature and geometry to achieve differing elution times for each ion present and being determined, and ordinarily to achieve elution of all the ions of one sign before elution of the ions of the opposite sign, e.g., all the anions before the cations. The effluent from each column is joined through a second stream splitter and the resulting single stream is directed to a conductivity cell with associated readout means. The effluent from the conductivity cell may be discarded but is ordinarily passed through clean-up resin bed means and cycled back to the eluant water reservoir. Preferably means are provided for (1) substituting columns with different resins and bed depths for specific analyses, (2) occasionally flushing the sample solution delivery system with bactericide, or (3) running known standard solution.

Abstract: A method of introducing a sample into a separation column includes introducing the sample into a trap column, isolating the trap column from ambient atmosphere and pressurizing the trap column to a first pressure while the trap column is isolated from ambient atmosphere, providing a fluid connection between the trap column and the separation column after pressurizing the trap column to the first pressure, supplying the sample from the trap column to the separation column.
