Embodiment Construction

[0025] 1. The control part of the industrial computer: the industrial computer does not need any modification, and uses self-compiled software (this software compilation is very easy for ordinary technicians in the field of software technology) to issue instructions and monitor the work of the whole machine, using the existing three Two data serial ports, one of which is connected to the remote control line for remote control and sending of result data; the other two serial ports are connected to the solenoid valve control components placed inside the chemiluminescence instrument for reagent delivery and mixing processes control.

[0026] 2. The setting of the chemiluminescence instrument: the optical sensor uses a low-noise, high-sensitivity, wide-wavelength photomultiplier tube. According to the photoelectric conversion principle of the photomultiplier tube, the power transformer adopts a power transformer with low current noise and stable output, and uses a special Dust-pro...

Abstract

This invention relates to a chemical luminous detector used in on-line monitoring / detecting pollutants in water samples including: a fluid transportation part, a chemical luminous monitor-detect part and a control part of a working control machine, in which, the reagent and a water sample to be tested enter into the screw channel of the chip of the flow cell of the detection part via their transporting parts then to be discharged from the outlet of waste solution after being mixed, the screw channel of the flow cell chip is opposite to the photosensitive window of a multiplier phototube and the original signals are connected with the input of the work control machine via a high resistance operation amplifier, a high frequency modem, a signal processor and a 16 A / D converter.

Description

technical field [0001] The invention relates to a fully automatic, on-line monitoring / detection chemiluminescence analyzer using chemiluminescence analysis for water body pollutants. Specifically, it is a chemical that can be used for the monitoring / detection of water body pollutants such as seawater, river water, tap water, drinking water, domestic sewage, industrial wastewater, etc., and uses chemiluminescence technology for on-line monitoring / detection of pollutants in water samples. Luminescence detector. Its pollutants can include inorganic pollutants as well as organic pollutants. Background technique [0002] Chemiluminescence and bioluminescence are ubiquitous phenomena in nature. Although some chemiluminescence and bioluminescence were discovered very early, in-depth research on their reaction mechanism and analytical applications began in the 1960s. On the one hand, due to the development of modern electronic technology and high-sensitivity photoelectric sensors,...
