The invention discloses a temperature control liquid inlet device for a series continuous flow analyzer. The temperature control liquid inlet device comprises a reagent tube, a reagent tube holder, aliquid medium, a temperature pre-regulation heater capable of regulating a temperature, a low-temperature heating sleeve, a temperature sensor, a liquid medium temperature sensor, a multi-passage digital display temperature controller and a container; the inside of the container is filled with the liquid medium; the front segment part of the reagent tube is fixed inside the container by the reagent tube holder; and the rear segment part of the reagent tube is coated with the low-temperature heating sleeve and the temperature sensor. The temperature control liquid inlet device is simple in structure, low in cost, long in service life and good in heat preservation effect; application of the series temperature control liquid inlet device effectively prevents crystallization of a liquid inletreagent in a flowing pipeline due to a low temperature so as to obviously improve accuracy and precision of a detection result and ensure successful operation of detection; and moreover, the temperature control liquid inlet device is high in safety, easy to operate and very suitable for instrument sample introduction of a laboratory in a non-constant-temperature environment on the low-temperatureweather, and has excellent application prospect.

Description

technical field [0001] The invention belongs to the technical field of chemical analysis and detection, in particular to a temperature-controlled liquid inlet device for a serial continuous flow analyzer. Background technique [0002] The continuous flow analyzer is a device that completes the physical mixing and chemical reaction of reagents in the pipeline at the same time, and then performs analysis on the basis of steady-state conditions. In order to facilitate the observation of the reaction state of the solution, all pipelines of this type of instrument are exposed to the air , so the temperature will have a direct impact on the reaction system. The solubility of a liquid solution at different temperatures will have a direct impact on the test results. When the external ambient temperature is low, the solubility of the reaction substance in the liquid system will decrease, resulting in incomplete reaction, and even the precipitation of crystals, which will cause block...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that when the sample is measured by the continuous flow method, the deviation of the sample detection result is too large due to the low temperature, the baseline drifts, and even the reagent crystallizes to cause the blockage or collapse of the pump tube; to provide a temperature control system for a series continuous flow analyzer The liquid inlet device is used to ensure that the reaction solution is kept at the temperature of the reaction system at low temperature, so as to prevent the incomplete reaction caused by the crystallization caused by the low temperature before the reagent enters the reaction heating pool, and the phenomenon that the detection error or failure is caused by the clogging or cracking of the pump tube and the detection error or failure is improved. The success rate of testing samples
