Description
Technical field
The utility model relates to the chromatograph technical field, refers to a kind of liquid chromatograph especially.
Background technology
Liquid chromatograph is the difference of utilizing potpourri distribution ratio between liquid-solid or immiscible two kinds of liquid, potpourri is carried out first separation, then the instrument of Analysis and Identification.Liquid chromatograph generally is made up of several parts such as reservoir, pump, injector, chromatographic column, detecting device, registering instruments.Mobile in the reservoir squeezed into system by high-pressure pump, sample solution enters mobile phase through injector, flowed and be written into mutually in the chromatographic column, because each component in the sample solution has different partition factors in two-phase, when in two-phase, doing relative motion, the assigning process of the absorption-desorption of process repeated multiple times, each component produces bigger difference in translational speed, being separated into single component flows out in post successively, during by detecting device, sample concentration is converted into electric signal and is sent to registering instrument, and data print with the collection of illustrative plates form.Existing liquid chromatograph mainly contains following technical deficiency: one, single plunger infusion pump commonly used exist that O-ring seal is easy to wear to cause leakage, and measuring accuracy is not high; Two, the detecting device wavelength coverage is short, and it is low to detect the analysis sensitivity; Three, detect data and be not easy to inventory analysis etc., demand urgently improving.
The utility model content
The purpose of this utility model be to provide a kind of transfusion steadily, long service life, the detecting device wavelength coverage is wide, and detects the liquid chromatograph that data are easy to inventory analysis.
For realizing the purpose of this utility model, intend by the following technical solutions:
A kind of liquid chromatograph is characterized in that: comprised solvent bottle, double plunger constant current infusion pump, injector, chromatographic column, spectrophotometric detector, waste liquid bottle, data processing work station, LCD display system and RS232 data-interface; On the transmission route of phase that flows, solvent bottle, double plunger constant current infusion pump, injector, chromatographic column, spectrophotometric detector are connected successively with waste liquid bottle; Described data processing work station is connected on the spectrophotometric detector, and described LCD display system links to each other with the data processing work station, shows to detect data; Described RS232 data-interface links to each other with the data processing work station, will detect data transmission and carry out inventory analysis again to computer.
As preferably, described spectrophotometric detector light source adopts the combined light source of deuterium lamp and tungsten lamp.
Compared with prior art, infusion pump of the present utility model adopts double plunger constant current infusion pump, reduced the influence of ring wear to measuring accuracy, prolonged serviceable life, adopted the combined light source of deuterium lamp and tungsten lamp simultaneously, the optical source wavelength wide ranges, can accurately detect the moving phase of more multithread, the RS232 data-interface is set in addition, the data transmission that detects to computer, is convenient to storage and is utilized analysis software to carry out data analysis.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
Fig. 1 has illustrated the structure of the utility model embodiment, and the utility model liquid chromatograph has comprised solvent bottle, double plunger constant current infusion pump, injector, chromatographic column, spectrophotometric detector, waste liquid bottle, data processing work station, LCD display system and RS232 data-interface; On the transmission route of phase that flows, solvent bottle, double plunger constant current infusion pump, injector, chromatographic column, spectrophotometric detector are connected successively with waste liquid bottle; Adopt double plunger constant current infusion pump, reduced the influence of ring wear to measuring accuracy, prolonged serviceable life.The spectrophotometric detector light source adopts the combined light source of deuterium lamp and tungsten lamp, and the optical source wavelength wide ranges can accurately detect the moving phase of more multithread.The data processing work station is connected on the spectrophotometric detector, and described LCD display system links to each other with the data processing work station, shows to detect data; The RS232 data-interface links to each other with the data processing work station, and the data transmission that detects to computer, is convenient to storage and is utilized analysis software to carry out data analysis.
More than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the instructions just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.
