Abstract

The invention relates to a multifunctional multi-channel sample loading device for a permanganate index analyzer. The multifunctional multi-channel sample loading device for the permanganate index analyzer comprises a shell, four groups of sample loading units, a four-way reversing valve, and a mobile sample loading head, wherein the sample loading units aremounted in the shell and used for independently adding reagents required for a test, and each group of sample loading unitscomprises a syringe pump; a pure water sample injection port, a reagent sample injection port, a sample discharging port, and a syringe pump connection port are formed in the four-way reversing valve correspondingly,and the four-way reversing valve isconnected with the syringe pump through the syringe pump connection port; and the mobile sample loading head is movably arranged in the shell and horizontally moves in the shell, and the mobile sample loading head is connected with the sample discharging port of thefour-way reversing valve. Compared with the prior art, the multifunctional multi-channel sample loading device for the permanganate index analyzer adopts a 4-channel sample injection system design, cross-contamination between different reagents is effectively avoided, and reliability of experimental result data is improved; no pipeline is reused, the cumbersome reused pipeline cleaning and liquidthrowing processesare reduced, liquid addition efficiency is improved, and analysis and measurement time are saved.

Description

technical field

[0001] The invention relates to the technical field of permanganate index analyzers, in particular to a multifunctional multi-channel sampling device for permanganate index analyzers. Background technique

[0002] In the permanganate index analysis experiment, chemical reagents such as sulfuric acid or sodium hydroxide solution, potassium permanganate solution, and sodium oxalate solution need to be added in different steps. The accuracy and parallelism of the sample amount are poor, and the experiment is a conditional experiment. The amount and speed of the sample amount directly lead to the difference in the measurement results, and there are obvious disadvantages.

[0003] Along with the research and development of automation instrument, the device that adopts mechanical pump to replace manual sampling gradually appears on the market, discloses a kind of fully automatic permanganate index analysis system as CN208297438U, is provided with controller, compri...
