Organic element analyzer is a kind of high-precision analytical instrument used to determine the content of various elements in substances. It burns or decomposes the sample at high temperatures, and uses the principle of chromatography to separate and detect the resulting gas, thereby accurately measuring the different elemental compositions in the sample. It can meet a wide range of needs from basic scientific research to industrial quality control. Through reasonable selection and use of this instrument, the analytical ability and efficiency of the laboratory can be greatly improved.
