Abstract
The utility model relates to the field of test devices, particularly to a high-speed and efficient tester capable of synchronously testing dissolved inorganic carbon and dissolved organic carbon. The high-speed and efficient tester comprises a sample tank, wherein the sample tank is connected with a reactor; the reactor is connected with a cooling device; the cooling device comprises a built-in water cooling system and is sealed, and a pipeline extends out of the cooling device and is connected to a carbon dioxide vacuum collection system. Extraction of dissolved inorganic carbon and extraction of dissolved organic carbon are integrated in one device. Therefore, the tester is smaller in size, needs fewer samples, and is simpler, more convenient and quicker to operate. The sealed samples are directly filtered into the reactor by adopting a negative pressure technology, the whole filtering process is performed under the vacuum condition, and the speed of the filtering can be improved by regulating the vacuum degree and the negative pressure. The high-speed and efficient tester avoids that a water sample contacts with the atmosphere, quickly, safely and smoothly extracts the dissolved inorganic carbon surely, processes organic carbon by adopting a photocatalytic oxidation technology, takes 2 hours to test one sample, is simple and convenient to operate, and saves time.
Description
Technical field
The utility model relates to the test unit field, and the dissolved inorganic carbon and the dissolved organic carbon that relate in particular to high-speed and high-efficiency are surveyed device altogether.
Background technology
This device is mainly used in the extraction of dissolved inorganic carbon and dissolved organic carbon in water sample, carries out
14C surveys year, then studies the process of the circulation of carbon in water, source and the groundwater contamination situation of indication water body carbon.
Traditional dissolved inorganic carbon and dissolved organic carbon are to adopt respectively two cover different devices to extract, and take up space, and the consumption sample size is large, is unfavorable for operation.
At present the dissolved inorganic carbon in water more for
14C research, still, owing to containing abundant carbonate particle in water, this part material tends to affect the reliability of test, these particle filterings need to be fallen, but in water, dissolved inorganic carbon very easily is subject to CO in atmosphere
2Pollution, need to filter under vacuum.
Because dissolved organic carbon content in water is little, so it is large to extract required sample size, length consuming time, adopt method (potassium permanganate etc.) oxidation of wet-chemical insufficient, limited dissolved organic carbon and existed
14C surveys the application on year.
Summary of the invention
The utility model content
