Multifunctional automatic sample injector

Abstract

A kind of multifunctional autosampler, it is characterized in that, mainly comprises 101-sample tray (horizontal rotor); 102-sample vial; 103-sample tray driving motor; 104-driving motor; 105-leading screw; 106-cleaning liquid 107‑base; 201‑sampling needle; 202‑washing needle; 203‑slider; 204‑spring; valve; 301-port of multiport valve and 201 injection needle; 302‑port of multiport valve and 202 cleaning needle; 303‑test water in line with laboratory use; 304‑cleaning solution bucket (bottle) (such as acid solution or Alkaline solution); 305-Reagent barrel (bottle); 306-Waste liquid barrel (bottle); 307-Mixed reactor; 308-Standard solution barrel (bottle). It can be used for automatic sampling in the determination of seawater, high-chloride and high-salt wastewater, surface water, groundwater, drinking water, domestic sewage, and industrial wastewater; it can be used for automatic sampling in laboratory determination, online determination, and emergency portable on-site determination.

Description

technical field [0001] The invention relates to the fields of analytical chemistry and automatic control, in particular to an automatic sample injector. Background technique [0002] There are many international and domestic autosamplers on the market, but there is a lack of autosamplers that use horizontal rotors and have the function of centrifuging the sample supernatant and sedimentation; [0003] Rectangular sample trays on the market generally have cleaning pools, but having a cleaning pool in a circular sample tray is not conducive to automatic control and programming. This project will make up for this defect. [0004] Most of the existing autosamplers have single functions, are expensive, and need to occupy a large space. [0005] The transmission system in the existing three-dimensional mechanical motion platform is prone to failure, the parts are easily damaged, vibration will occur during the motion, the motion is unstable, and the anti-interference ability is p...

[0003] Rectangular sample trays generally have cleaning pools on the market, but having cleaning pools in circular sample trays is not conducive to automatic control and programming. This project will make up for this defect

[0004] Most of the existing autosamplers are single-function, expensive, and require a large space

[0005] The transmission system in the existing three-dimensional mechanical motion platform is prone to failure, the parts are easily damaged, vibration will occur during the motion, the motion is not stable, and the anti-interference ability is poor, and motion failure will occur due to a slight impact from the outside
