At the beginning of its establishment, the School of Chemical Engineering at Lanzhou University has gone through 70 years of construction and development. With the care and support of leaders at all levels and various sectors of society, and the unremitting efforts of several generations, it has formed a strong and excellent teaching and research collective, and is renowned at home and abroad for cultivating high-quality talents and creating high-level achievements. It has become an important base for the cultivation of high-level chemical and chemical talents and scientific research in the western region of China.

Lanzhou UniversityThe predecessor of the School of Chemistry and Chemical Engineering was1946The Department of Chemistry at National Lanzhou University, established in the autumn of, is one of the earliest established chemistry departments in China.1985Established annuallyState Key Laboratory——State Key Laboratory of Applied Organic Chemistry（2003Renamed asState Key Laboratory of Functional Organic Molecular Chemistry），1998In the year, the College of Chemistry and Chemical Engineering was established.

The College of Chemistry and Chemical Engineering and the State Key Laboratory of Functional Organic Molecular Chemistry are approved as the first level discipline doctor authorized units of chemistry and one of the earliest "basic discipline (chemistry) talent training bases" in the country. It has a post doctoral research station in chemistry and a national key discipline in organic chemistry. Chemistry is a national discipline“985”And“211The key disciplines of "Engineering" and the Gansu Province Youth Science and Technology Innovation Demonstration Base have distinctive majors of the Ministry of Education's higher education institutions (Chemistry and Functional Materials) and corresponding majors of national strategic emerging industries (Functional Materials).

Teaching and Research Laboratory30000mThe university chemistry experimental teaching center has teaching laboratory area6000m.

The State Key Laboratory and the Analysis and Test Center have a number of advanced large-scale instruments and equipment, such as cryogenic NMR spectrometer, micro focus rotating target single crystalXAdvanced instruments such as X-ray diffractometer and laser confocal Raman spectrometer have reached the advanced level of similar disciplines in domestic universities in terms of teaching and research conditions.

At the beginning of its establishment, Qingdao Ailun General Technology Co., LtdYC7000As an excellent instrument for detecting anions in water, the Type II ion chromatograph was selected through rigorous organization and multiple selections, and finally decided to use the one developed and produced by our companyYC7000Type ion chromatograph, which participated inCISILE 2017The selection process for the Independent Innovation Award, relying on strong capabilities and intense competition, has wonCISILE 2017Gold Award for Independent Innovation, with a high degree of advanced and automated technology, has contributed to the testing work of this catalytic center for many years. In early July, the company's after-sales personnel visited the School of Chemistry and Chemical Engineering at Lanzhou University and found that the instrument was in good condition and could meet daily work needs after inspection.

YC7000The Type II ion chromatograph is a new type of ion chromatograph developed by our company for the domestic market. It adopts the temperature controlled TP detector currently available in China, which has temperature stability. It is shielded by a new material shell that is resistant to signals and interference, and has a lower and more stable baseline. Moreover, the built-in intelligent chip also stores standard spectra, which can be directly used for software validation and training.
This instrument is equipped with three different injection modes: manual injection, electric injection, and automatic injection, which can be freely switched between, providing users with an automated and user-friendly instrument application experience. At the same time, different detectors such as conductivity detector, UV detector, and electrochemical detector can be selected for a wider range of applications, including solid waste, electrolytic plating industry, nuclear industry, sewage treatment, environmental monitoring, food and drug, hydrogeology, health and epidemic prevention, etc.
