In honor of Professor Kiyokatsu Jinno.

At the end of July 2016, Professor Kiyokatsu Jinno retired as an editor of Analytical and Bioanalytical Chemistry (ABC). He was one of the six founding editors when the first issue of the journal appeared in January 2002. Kiyokatsu Jinno (Fig. 1) received his BA (1968), MS degree (1970), and PhD (1973) all from Nagoya University in Nagoya, Japan, working with Professor Daido Ishii, a prominent Japanese separation scientist. Professor Jinno’s doctorate degree, however, was in engineering with research in non-destructive elemental analysis using neutron activation analysis. He then spent the next five years as a research scientist in the Integrated Circuit Laboratory at the Toshiba Research and Development Center working on the development of the dry plasma etching process and electron beam lithographic techniques for large-scale integrated circuits, which he described as Ban active and interesting field^ [1]. In 1978 he was invited to become an associate professor in the School of Materials Science at Toyohashi University of Technology (TUT), a new national technical university just opening at the time of his arrival. At TUT he had been expected to work in the area of radiochemistry using an accelerator that was planned to be built on campus. Unfortunately, the accelerator never appeared, and Professor Jinno was left to find a new area of research. Following the advice of his mentor, Professor Ishii, he chose micro-column liquid chromatography (micro-LC) as his area of research. Professor Jinno remained at TUT until his retirement in 2014 as Full Professor and Vice President of the University. Professor Jinno’s decision to move from activation analysis and elemental analysis to the emerging area of LC was monumental, and he soon became an internationally recognized leader in the field of separation science and related sample preparation techniques. His areas of research during his career span the broad scope of separation science including retention mechanisms and molecular recognition in LC, design of novel stationary phases, development of capillary separation techniques, miniaturized sample preparation techniques and their combination with liquid-phase separations, hyphenated techniques in chromatography and spectroscopy, and the use of computers in separation sciences. He has contributed to a wide range of separation techniques, beyond his primary focus in LC, including micro-LC, capillary electrophoresis, supercritical fluid chromatography (SFC) and extraction (SFE), electrochromatography, gas chromatography, gel permeation chromatography, high-performance thin-layer chromatography, chiral chromatography, solid-phase extraction (SPE), and solid-phase microextraction (SPME). Professor Jinno has been a prolific author with over 310 original research papers, 35 review articles, 39 book chapters, and four books (as author and editor). The exceptional number of review articles, book chapters, and books illustrates the broad range of his contributions. He has presented over 90 plenary and invited lectures at international symposia on chromatography and analytical chemistry. In 2001 a book titled A Century of Separation Science was published highlighting the careers and experiences of many of the founding leaders in the field of separation science. In Professor Jinno’s contribution, BMy Life in Separation Science: Study of Separation Mechanisms^ [1], he states that Bhis contribution to the development of separation science can be divided into at least two main categories: hyphenated * Stephen A.
