Liquid chromatograph pump flow calibration device

Abstract

The invention discloses a liquid chromatograph pump flow calibration device which comprises a case body and a connecting plate, a weighing balance is arranged in the case body, a container is arranged at the top of the weighing balance, a connector is arranged at the top of the container and fixedly connected with the case body, a calculator body is arranged in the case body, and a liquid chromatograph pump is arranged in the calculator body. The computer case has the beneficial effects that the unification of flow calibration is realized by adding the interface, the weight detection in a container is realized by adding the weighing balance, the calculation accuracy is improved by adding the calculator body, and the calculation accuracy is improved. By adding the calculator body, the uniform calculation of the collection time, the mobile phase density and the collection times by the calculator body is realized, by adding the printer body, the printing of the structure calculated by the computer body by the printer body is realized, and by adding the display screen, the numerical value display of the uniform calculation of the collection time, the mobile phase density and the collection times is realized.

Description

Technical field [0001] The present invention relates to the field of flow calibration, and is specifically a liquid phase chromatograph pump flow calibration device. Background technique [0002] The liquid chromatograph utilizes the difference between the mixture between the mixture between the liquid-solid or uncoisible liquid, and the mixture is first separated, and the identified instrument is then analyzed. The system consists of several parts of the reservoir, pump, injector, column, detector, recorder, etc. The flow phase in the reservoir is driven into the system by a high pressure pump. The sample solution is entered into the mobile phase, and is filled into the color column (fixed phase), since each component in the sample solution has in two phases Different allocation coefficients, when relatively movement in two phases, after repeated multiplex-desorption dispensing processes, each component produces a large difference in moving speed, separated into a single compone...
