Abstract

The invention discloses a liquid-chromatography and atomic-spectroscopy combined system, which comprises a mobile phase bottle, a proportional valve, a liquid-phase pump, a quantitative loop, an injection valve, a cleaning valve, a chromatographic column and an atomic spectral detector, wherein the mobile phase bottle, the proportional valve, the liquid-phase pump, the injection valve, the cleaning valve, the chromatographic column and the atomic spectral detector are sequentially connected; the injection valve is a two-position six-way valve and comprises a first inlet, a first outlet, a first interface, a second interface, an injection port and an overflow port; the first interface and the second interface are connected with the quantitative loop; the cleaning valve is a two-position flow valve and comprises a second inlet, a second outlet and a liquid outlet; the first inlet is connected with the liquid-phase pump; the first outlet is connected with the second inlet; and the second outlet is connected with the chromatographic column. According to the liquid-chromatography and atomic-spectroscopy combined system, the loss of a liquid-phase system is avoided and the service life of the liquid-phase system is prolonged.

Description

technical field [0001] The invention relates to the technical field of analysis and detection equipment, in particular to a combined liquid chromatography atomic spectrum system. Background technique [0002] Liquid chromatography is the mainstream method of analysis and detection at present. The liquid chromatograph mainly includes sample injector, liquid phase pump, chromatographic column, ultraviolet detector, molecular fluorescence and other detectors. The specific analysis process is that the liquid sample is injected by the sample injector. Finally, the components of the compounds are separated when the liquid phase pump pushes through the chromatographic column, and finally the detectors generate signals respectively. Liquid chromatography is widely used in the detection and analysis of various organic compounds in food, environment, disease control and other systems because of its good separation and purification capabilities, and can characterize the content of vari...
