The invention provides an intelligent automatic switching multi-channel ion chromatographic column connecting device. The intelligent automatic switching multi-channel ion chromatographic column connecting device comprises a fixed base, a plurality of ion chromatographic columns, a control panel and two multi-channel chromatographic column connecting devices, wherein the control panel is provided with a display screen; each multi-channel chromatographic column connecting device is provided with a plurality of fluid channels, and a fluid flows through different ion chromatographic columns by rotatably switching the fluid channels; the multi-channel chromatographic column connecting devices are arranged at the top and the bottom of the fixed base respectively; the control panel is in circuit connection with the two multi-channel chromatographic column connecting devices respectively and is used for controlling switching of the fluid channels of the multi-channel chromatographic column connecting devices; the ion chromatographic columns are connected in parallel between the corresponding fluid channels of the two multi-channel chromatographic column connecting devices by virtue of a chromatographic column connecting pipe. When being replaced by using the intelligent automatic switching multi-channel ion chromatographic column connecting device, the ion chromatographic columns do not need to be manually dismounted and re-mounted, one-key automatic switching control sampling can be performed on different chromatographic columns, the chromatographic columns are convenient to periodically wash and maintain, and the intelligent automatic switching multi-channel ion chromatographic column connecting device is simple to operate, low in cost and easy to popularize.
Description
technical field [0001] The invention belongs to the field of laboratory analysis instruments, in particular to an intelligent automatic switching multi-channel ion chromatographic column connection device. Background technique [0002] Ion chromatography is a chromatographic method for the separation and analysis of ionic substances based on the charge interaction between ionic compounds and ionic functional groups on the surface of the stationary phase; the most basic components are mobile phase containers, high-pressure infusion pumps, and samplers , chromatographic columns, detectors and data processing systems. The high-pressure infusion pump delivers the mobile phase to the analysis system at a stable flow rate (or pressure), and introduces the sample through the injector before the chromatographic column, and the mobile phase brings the sample into the chromatographic column and performs ion exchange directly between the ion exchange resin (i.e. retained on the column...
