Embodiment Construction

[0027] Such as figure 1 As shown, the automatic analyzer of the present invention mainly includes peristaltic pumps a, b2, fluid meter b, multi-channel sampling valve c, first solenoid valve d and digester e. These components / elements / devices are installed on the casing of the analyzer, and the electric control device and the casing are prior art, and will not be described in detail here. The multi-channel sampling valve is connected to standard 2, standard 1, water sample, waste sample, potassium dichromate, mercury sulfate and silver sulfate, namely K1, K2 to K7. Peristaltic pumps and fluid meters are used to draw specific volumes of samples, water samples or reagents. Its working process is as follows: rinse the measurement water sample, container and digestion tube; turn on the peristaltic pump to inject samples; turn on the peristaltic pump to add reagents; mix water samples and reagents; after the solution develops color, turn on the peristaltic pump to discharge the so...

Abstract

The invention discloses a general high-precision automatic analyzer. The general high-precision automatic analyzer comprises a peristaltic pump, a fluid meter, a multiway sample feeding valve, a first electromagnetic valve and a digester which are connected in sequence, wherein the digester comprises a shell, a digestion pipe fixed in the shell, a photoelectric emitter and a photoelectric receiver which are fixed on the inner side of the shell, as well as a second electromagnetic valve which is fixed to the shell and is directly communicated with the digestion pipe; the digestion pipe is positioned on a light path between the photoelectric emitter and the photoelectric receiver. The photoelectric receiver and emitter are arranged on the inner side of the shell, so that the working temperature is conveniently controlled, the influence of temperature fluctuation on data measurement is reduced, and thus the data precision is improved; meanwhile, the electromagnetic valve is directly communicated with the digestion pipe instead of a connecting pipe, so that the analyzed substance emission space in the digestion pipe is reduced, and the data precision is improved.

Description

technical field [0001] The invention relates to an analyzer, in particular to a universal high-precision automatic analyzer. Background technique [0002] Analyzer is an important equipment, which has important applications in scientific research, industrial production and environmental monitoring. There are many kinds of existing analyzers, and the structure / principle is basically the same. As the requirements for the accuracy of monitoring data become higher and higher, the existing analyzers can no longer meet the needs of customers. It is necessary to improve their structures and functions to improve The precision of the detection analysis. Contents of the invention [0003] The object of the present invention is to provide a general-purpose high-precision automatic analyzer aiming at the problems existing in the prior art. [0004] Technical solution: A general-purpose high-precision automatic analyzer, including a peristaltic pump, a fluid meter, a multi-channel sa...
