Dr. Du’s strength is in the development of methods for GC/MS, SFC-MS and LC-MS applied to food safety, environment safety, medicines and polymer materials. She also is extremely experienced in spectral analysis using IR, NMR and MS approaches for structural deduction. Through solving many difficult problem for many enterprises, she has established good cooperation with many companies, such as the Chinese academy of inspection and quarantine, State Grid Company of China, Tongfang NUCTECH Co. Ltd, Beijing Tong Ren Tang Chinese Medicine Co. Ltd. and many universities.
As visiting scholar, Dr. DU has studied at Purdue University in the United States in 2012. At the same time, Dr. Du began a cooperation with Waters Corporation and established the polymer additives library (more than 300 kinds of material) which commonly used in plastic packaging materials. Based on the additive polymer library, the method to identify main leachables-polymer additives in medical products was developed by ultra-performance liquid chromatography-quadrupole time-of-flight-mass spectrometry (UPLC-QTOF MS) and realized the rapid screening extractables and leachables. As a director or participants of the National Science-technology Support Plan Projects, National nature Science Foundation, philanthropic projects supported by the General Administration of Quality Supervision, Inspection and Quarantine(GAQSIQ) and other projects from the enterprises. Dr. Du has public more than 80 papers in Analytical Chemistry, Journal of Chromatography A, Journal of Hazardous Materials, Food Chemistry, so on. About packaging materials compatibility research, Dr. DU published 8 relating dissertations.
