Associate Professor Lan’s research spans agricultural standardization research and the development of agricultural product standard samples, leading to materials with properties useful in the detection of trace substances in complex matrices and healthcare. Dr. Tao Lan began his formal studies in environmental engineering at Nanjing University of Science & Technology (B.S. 2002 & M.S. 2006). He obtained his Ph.D. in applied chemistry from Shanghai Jiao Tong University in 2014, and performed postdoctoral research with Prof. Shaorong Liu at the University of Oklahoma. He joined the China National Institute of Standardization in 2016 and was appointed as Associate Professor in 2018. During the past five years, he has presided over and participated in 12 national, provincial, and ministerial projects, prepared more than 20 national reference materials for natural products such as gastrodin and salidroside, with leading and participating in 20 national and industrial standards, and applied for more than 20 national invention patents and utility model patents such as a tannic acid band-aid and its preparation method, of which 8 patents were authorized. He has published more than 30 academic papers on the quality of agricultural products, healthy food, and testing methods in SCI journals such as Food Chemistry, and Chemosphere, and has written one English monograph. He reviewed more than 30 papers for Food Chemistry, Analytical Chemistry, and other magazines. And as a guest editor, he contributed 3 issues to the Chinese Journal of Food Industry Science and Technology.

Collection Overview

The detection of trace substances in complex matrices has always been the focus of research in the field of analytical chemistry. With rapid improvements in the sensitivity of analytical instruments, relevant research has entered a period of accelerated development, but a sharp improvement in sensitivity also leads to the reduction of the resolution, which, in turn, increases the requirement for the pretreatment and purification of samples. Since the invention of QuEChERS in 2003, it has been widely welcomed by analytical chemists because of its simple operation and universality of application. With the introduction of various porous carbon materials, its performance has been greatly improved and its use threshold has been reduced, which has enabled it to gradually enter the national standardized methods.

This collection aims to share standardized protocols for QuEChERS application; promote broader global access to existing methods; open network production for research collaborations anew. We trust this approach will encourage a myriad of scientists to take part in this global effort in a trans-disciplinary manner, towards renewed progress in the detection of trace substances in complex matrices.
