Embodiment 1

[0068] The sample introduction system 100 and the detection system 500 are connected in parallel with the measurement water system 200, the raw water sample system 300, and the oxidized water sample system through pipelines. 300 and one of the oxygenated water sample system 400 switches the switching device 12 that communicates.

[0069] The determination water system 200 is normally connected to the sampling system 100 and the detection system 500 respectively;

[0070] The cleaning system 600 is arranged before the detection system 500 and communicates with the detection system 500;

[0071] The control system 800 is electrically connected with the sampling system 100 , the detection system 500 , the measurement water system 200 , the raw water sample system 300 , the oxidized water sample system 400 , and the switching device 12 and controls their work.

[0072] Among them, such as figure 1 , 2 As shown, the function of the sampling system 100 is to input the water samp...

Embodiment 2

[0098] The first system is a sampling system 100 for continuously inputting water samples;

[0099] The second system is used to process the water samples, including three systems in parallel: a measurement water system 200 for deionization treatment to obtain measurement water without any impurities, a raw water sample system 300 for keeping the original water samples without any treatment, and Water samples are oxidized to obtain an oxidized water sample system 400; the front ends of the measurement water system 200, the raw water sample system 300, and the oxidized water sample system 400 are all connected to the first system, and the back ends are all connected to the third system;

[0100] The third system is a detection system 500 for detecting the measured water, raw water sample or oxidized water sample in the second system and discharging the detected waste water;

[0101]The fourth system is connected to the cleaning system 600 before the detection system 500 and int...

Abstract

The invention discloses an online total organic carbon water quality analyzer and an online total organic carbon water quality analyzing method. The analyzer comprises a sample introduction system, a detecting system, a control system and a cleaning system, wherein a pipeline fitted between the sample introduction system and the detecting system is connected in parallel with a measured water system, an original water sample system and an oxidized water sample system and provided with a switching device; the measured water system is respectively and normally communicated and connected with the sample introduction system and the detecting system; the cleaning system is arranged in front of the detecting system and communicated with the detecting system; and the control system is electrically connected with the sample introduction system, the detecting system, the measured water system, the original water sample system and the oxidized water sample system and used for respectively controlling the sample introduction system, the detecting system, the measured water system, the original water sample system and the oxidized water sample system to work. The analyzing method comprises the following steps of: A. establishing four sequentially-connected systems; B. establishing the control system and controlling the actions of all the system in the step A; C. preparing for detection; and D. detecting. The online total organic carbon water quality analyzer is capable of realizing online detection, high in detection precision, low in detection limit and simple to operate.

Description

technical field [0001] The invention belongs to the technical field of water quality detection, and relates to a water quality detector, in particular to an online total organic carbon water quality analyzer and an online total organic carbon water quality analysis method. Background technique [0002] Total organic carbon (TOC) is a comprehensive index to evaluate the total organic content in water. The amount of TOC in water directly reflects the degree of water pollution by organic matter. The TOC detection method is a method advocated by the FDA for evaluating all carbon-containing organic substances in the tested water samples, and is widely used in quality control, production and cleaning verification of related pharmaceutical production equipment. For pharmaceutical water (WFI), TOC is already a rigid standard. There are clear texts in the United States Pharmacopoeia <USP 643>, European Pharmacopoeia <EP 2.2.44>, Japanese Pharmacopoeia <JP 16> and Ch...
