Abstract
The utility model provides a total organic carbon analyzer for low-concentration total organic carbon water samples, and the analyzer is characterized by consisting of an aeration tank; a filter and a sample feeder are connected with the aeration tank; hydrochloric acid is connected with the aeration tank through a metering pump; the sample feeder is connected with a combustion system and a sampling pump which is used for measuring offline samples and is controlled by a computer program; nitrogen is respectively connected with the sample feeder and the combustion system through flow control units; and the combustion system, a dehumidifier, an infrared instrument, a data processing system, a signal output system and a display screen are sequentially connected. The device overcomes the defects of the prior art, the minimum threshold for the determination of total organic carbon is reduced by adopting a ceramic valve with rated volume for quantitative sample feeding measurement and the infrared instrument with high response time, so that the errors in the analysis to the total organic carbon combustion are reduced, and the accuracy in a low-concentration total organic carbon water sample test is improved.
Description
Technical field
The utility model relates to a kind of TOC analyser for low concentration total organic carbon (total organic carbon, English referred to as TOC) water sample, belongs to TOC analyser technical field.
Background technology
At present, environmental problem receives increasing concern as the key factor that affects social development.How understanding Environmental Status, solve reality or potential environmental problem, coordinate the relation between the human and environment, make society can keep sustainable development, is all over the world all in the problem of making great efforts to solve.Existing environmental monitoring system can't satisfy the monitoring requirement of conventional project, and the TOC analyser that is applied to the on-line monitoring field has a lot of advantages, and it can show the content of the total organic carbon in the water outlet intuitively, the variation of reaction water quality.Yet the measurement range minimum of present TOC analyser can only arrive 0-20mg/L, and the TOC content in good water sources ground water, seawater and the qualified tap water output water generally only has 3-4mg/L.Although existing TOC analyser also can be analyzed, its full scale measuring error reaches 3-4%F.S, and relative error reaches 20%-25%.As seen, the deviation of existing TOC analyser test low concentration TOC water sample is larger, can not measure exactly for the water sample below the TOC content 3mg/L.
Summary of the invention
The purpose of this utility model provides a kind of TOC analyser that can accurately test low concentration TOC water sample.
In order to achieve the above object, the technical solution of the utility model provides a kind of TOC analyser for low concentration TOC water sample, it is characterized in that: comprise the aeration tank, filtrator all links to each other with the aeration tank with injector, and hydrochloric acid is connected with the aeration tank through volume pump; Injector also connects combustion system and is used for the sampling pump by computer program control of off-line sample measurement, and nitrogen is connected with combustion system with injector respectively through flow controlling unit; Combustion system, dehumidifier, infrared instrument, data handling system, signal output system link to each other successively with display screen.
Preferably, described injector is ceramic valve.
Preferably, described combustion system comprises flame tube, and the flame tube below is provided with heating arrangement.
Preferably, described data handling system is connected to form by data collection module and data processing unit.
A kind of TOC analyser for low concentration TOC water sample that the utility model provides adopts the ceramic valve quantitative sample injection to measure, and has reduced the error in dipping of water sample, has guaranteed that each sample size is identical; Adopt fast infrared instrument of response time, guarantee the Measurement accuracy under the low concentration.
The device that the utility model provides has overcome the deficiencies in the prior art, by ceramic valve and the employing fast infrared instrument of response time that adopts nominal volume, reduce the minimum threshold values that TOC measures, reduced the error of TOC combustion analysis, improved the accuracy of low concentration TOC water sample test.
Description of drawings
The structured flowchart of a kind of TOC analyser for low concentration TOC water sample that Fig. 1 provides for the utility model.
Embodiment
For the utility model is become apparent, hereby with a preferred embodiment, and cooperate accompanying drawing to be described in detail below.
