The analytical approach principle of total organic carbon, after removing the inorganic carbon in sample with watery hydrochloric acid, is burnt, make total organic carbon be converted into carbon dioxide, detect and provide the content of total organic carbon through infrared detector in high temperature oxygen air-flow.Total organic carbon analysis comprises sample pre-treatments and instrument detects two parts.Sample pre-treatments relates to the operations such as sampling, pulverizing, weighing, acidifying, drip washing, oven dry, complex steps.Wherein, in the mensuration of total organic carbon " in the sedimentogeneous rock " GB/T19145-2003 5.4 to wash control gauge fixed: acid-treated sample is placed in the porcelain crucible on nutsch filter, neutrality is washed till with distilled water, in avoiding instrument to detect, there is complicated thermal chemical reaction with organic in hydrochloric acid in high-temperature oxydation air-flow, may generate harmful even fatal hydrogen sulfide gas.At present, by the method mainly artificial ELUTION METHOD of distillation washing sample.Artificial ELUTION METHOD utilizes the sample crossed by HCl treatment to be placed in the porcelain crucible on nutsch filter, with distilled water drip washing sample, the negative pressure utilizing vacuum pump to produce separates the hydrochloric acid in porcelain crucible and distilled water mixed liquor and sample, finally sample is washed till neutrality.Following problem is there is: 1, drip washing speed is slow, and inefficiency, can only wash one piece of sample at every turn in artificial ELUTION METHOD real work; 2, because sample size is many, the running time is long, and labour intensity is large; 3, inspiration acid gas in lessivation, can damage health; 4, in lessivation, water consumption is large, frequently adds water and affects work efficiency.
Utility model content
The purpose of this utility model is that inefficiency that above-mentioned prior art exists, labour intensity are large in order to overcome, acid gas adds water affect work efficiency problem on actual bodily harm, frequently, thus provides a kind of total organic carbon sample elution device.
The utility model is made up of Suction filtration device, support, bracket, elution device, and bracket is the rectangular faceplate being provided with circular groove, rack-mount; Suction filtration device is made up of vacuum pump, suction filtration surge flask and bottle,suction, and bottle,suction is placed in the circular groove of bracket, and bottle,suction was connected in series with suction filtration surge flask, vacuum pump successively by communicating pipe; Elution device is in series by buret, water inlet pipe, water storage box, and buret is positioned at above bottle,suction, the rack-mount end face of water storage box.
The beneficial effects of the utility model are: in total organic carbon sample analysis pretreatment process, tetrafluoroethene " O " RunddichtringO on the permeable crucible sleeve filling HCl treatment and cross sample is placed on bottle,suction, in permeable crucible, distilled water is injected by buret, drip washing sample, the negative pressure utilizing vacuum pump to produce is in the mixed liquor suction bottle,suction of the hydrochloric acid in permeable crucible and distilled water, thus the mixed liquor of the hydrochloric acid in permeable crucible and distilled water and sample are separated, in distilled water drip washing specimen, automatic drip washing capable of circulation, reduce acid gas to the injury of human body, reduce labour intensity, increase work efficiency, analytical cycle is shortened greatly, improve drip washing effect.
