Capillary electrophoresis- A bibliometric analysis

We have explored the history of the field of capillary electrophoresis using bibliometric methods. The analysis shows that 416 prolific researchers are connected in a single, large, co-authorship network based on publications on capillary electrophoresis between 1980 and 2021, with a few pioneers having remained active throughout much of this time period. Looking at research topics revealed electro-chemistry, sensors, nanotechnology and metabolomics as 'hot' topics, with fundamental method development being more 'mature', and reveal that capillary electrophoresis technology have matured over a 30-year time period, with research efforts moving from separations to quantitative measurements to biomedical applications. The citation patterns showed the strongest coupling between journals of similar scope.
