In this study, we have selected the papers in the chemometric field that were published between 2001 and 2015 in the six journals (Chemometrics and Intelligent Laboratory Systems, Journal of Chemometrics, Analytica Chimica Acta , Analytical Chemistry , Talanta and Journal of Chromatography A) to investigate the collaboration patterns and network. We reveal and visualize the collaboration patterns, publication trends, and research hotspots on chemometrics based on the datasets. The central chemometricians are then determined under different indexes. Finally, we discover that the largest component of the network is clustered into the "Big Europe" and "China-Changsha" community. The rest components in the network are also identified and explained. The results show the features of the collaboration patterns and network in chemometric research and present a new way to explore the zeitgeist in the area. • This paper researches the evolving collaboration patterns and network among chemometricians quantitatively. • We discuss the results on the publication and coauthor patterns, and most central authors, hot research topics. • The major components in the network can be interpreted by their geographical distributions. • The largest component of the network could be clustered into the "Big Europe" and "China Changsha" community.
