Title: Gas chromatographic analysis - branched stream of separated constituents is retained on support strip for direct comparison with chromatogram
Inventor: BEDNARSKI VALERY NICHOLAS
IPC: G01N30/82
Filed: 1972-09-23
Abstract: A method of gas chromatographic analysis of samples operates by breadking down the sample in a separation column into its separate constituents or compounds, so that these leave the column in succession; the constituents or compounds are identified in a detector, the detector signals being recorded in the form of a graph on a moving chromatogram sheet, the graph having peaks corresponding to the separate cpds. A partial stream is branched off from the flow leaving the separation column and is directed towards a support strip which is moved synchronously with the chromatogram sheet. This support strip pref. has a coating of an absorbing material. Pref., the support strip is of Al foil coated with alumina or silica gel. The method enables a direct comparison to be made between the peaks, indicating individual features on the chromatogram and the corresponding portions of material retained on the strip.

Patent DE-2310902-A1 (DE)
Title: Automatic halogen content control in liquids - by pulsed current supply to electrodes and discharging capacitor
Inventor: VALE DONALD PAUL DE
IPC: G01N27/06
Filed: 1973-03-05
Abstract: The halogen (chlorine) content in liquids (water in swimming baths and municipal water supplies) is determined by passing a pulsed current through a pair of electrodes in the liquid, in parallel to a capacitor which can be discharged depending on the liquid resistance. A measuring circuit with a high input impedance is used to establish when the capacitor voltage has dropped to a predetermined value and initiates the addition of chlorine to the liquid. The periodical repolarization of electrodes at high tension is saved. The application of a constant d.c. voltage would lead to increasing inaccuracies caused by galvanization, requiring a correction of the electrode impedance; this is not now necessary.
