Multichannel collection HPLC sample injection device and method

Abstract

The invention discloses a multichannel collection HPLC sample injection device and a method. The device comprises a sample suction system and a liquid chromatogram system, wherein the sample suction system comprises a ten-way valve, a deionized water bottle, an AXP pump and sample bottles; the liquid chromatogram comprises a six-way valve, a solution storage device, an analytical column and a detector; ten internal ports of the ten-way valve are respectively connected with nine sample bottles and one deionized water bottle; an outer port of the ten-way valve is connected with the AXP pump; thesolution storage device is connected with the six-way valve through an infusion pump system; both the analytical column and disposal bottle are connected with the six-way valve; the analytical columnis connected with the disposal bottle through the detector; and the six-way valve is connected with the AXP pump. The device is capable of replacing an automatic sample injector or a manual sample injection module in a liquid chromatograph, so that automatic sample injection analysis of multiple samples is realized and influences, on dynamic processes, of temperature and reaction liquid homogeneity are decreased or avoided to the greatest extent; and sampling and sample injection do not need to be carried out by manpower in real time, so that the working efficiency of experimenters is greatlyimproved, and plenty of real-time dynamic data can be obtained in unattended operation.

Description

technical field [0001] The invention relates to a sampling method, in particular to a multi-channel acquisition HPLC sampling device and sampling method. Background technique [0002] Most of the sulfur elements in ores (such as coal, iron ore, and gold ores) are in a low-priced state, and more SOx is released when the minerals are utilized, which is the main component of environmental pollution. It is currently a difficulty to process and desulfurize the ores before they are used. Both the efficiency and benefit of coal processing desulfurization need to be improved qualitatively, and the key lies in the research on the kinetic mechanism and regulation of sulfur chemistry that needs to be further discussed. In addition, in the past two decades, nonlinear kinetic phenomena have been discovered in the two-component system of oxidant-sulfur (-II) compounds, but the exploration of the reaction mechanism is far behind the research on the phenomenon, and it has not been very good...

Problems solved by technology

[0004] Traditional high-performance liquid chromatography usually uses manual injection to track the kinetic curve of the reaction process, or manually removes the titration plate and loads it into an autosampler for reaction tracking. Such methods cannot accurately locate the reactants. time dynamics
