Stoichiometric institute is the institute of JSIM, owns chemical detection rooms and the gas detection room,including two experienced senior engineer, three mid-level engineers. 　　The institute's goal is to maintain domestic advanced stoichiometric detection technology, and actively coordinate with the international chemical detection method, Do best to keep my standard’s comparability and volunteers in the domestic and international measurement. Stoichiometric Institute carried out various major chemical analysis of the testing and calibration equipment, gas detection equipment and a variety of test and calibration. Also in the development of gas component products, which are to go to many chemical plants, medical prevention unit, agricultural production monitoring and scientific research departments, the province physicochemical money for reliable and accurate active service units of reunification. 　　The institute currently has 40 or more communal society in Jiangsu provincial measurement standards. including GC-MS, online COD detector, auto emission gas analyzer, combustible gas alarm device, the alcohol concentration exhaled gas detector test in Jiangsu Province and East China region has a high level. 　　This institute owns first-rate detection technology, and take part in the state project in the highest stoichiometric ratio testing laboratories on behalf of Jiangsu Province. Over the past five years, the Institute has participated in more than a dozen countries over the project, achieving better results, get the consensus within the domestic industry.
