by the elutriation technology in narrow, size fractions and pack them in stain. less steel columns by the slurry tech, nique It took nearly another decade. for a column manufacturer to produce, reproducible stable and validated. HPLC columns that enabled their wide, application in the pharmaceutical and. chemical industry, The serious discussions on the pros.
and cons of porous layer beads versus, totally porous particles continued. over several years until spherical silica, particles took the floor For me it is. interesting that the same discussions, recently began again regarding the. pros and cons of columns packed with, sub 2 m porous silica particles and. core shell particles with a 1 6 m solid, core and a 0 5 m porous shell Four.
decades later we were finally able to, approach the limits of HPLC in terms. of column performance speed and, sensitivity, Josef became my primary mentor. in science and I developed a great, admiration of him as a person and. scientist until he passed away unex, pectedly in 2000 His successor was. Wolfgang Lindner with whom I have, a long standing collaboration and.
friendship, Jack J Kirkland My first meet, J F K Huber Vienna 1997 ing with Jack Kirkland dates back to. 1973 when I was visiting the American, At that time the world of high packed with these porous layer beads tycoons in chromatography who were. performance liquid chromatography However the column capacity column spread along the East Coast from Bos.

it started to snow I remember that, Peter F ldi Eli Grushka Roland Frei. and Milos Novotny were all there For, the first time we visited the cultural. sites of Nara with all the temples, Kyoto the old capital of Japan offered. many historical places among them, the wooden temple of the emperor of. In the following 20 years I vis, ited Kyoto nearly every year and had.
the opportunity to notice the social, changes in Japan During my visits I. also got to know the seniors in separa, tion science in Japan as well as the. newcomers including Nobuo Tanaka, Shigeru Terabe and Takao Tsuda. The others were scientists in the field, of adsorption and catalysis which was. and still is an active field of research, in Japan The senior Seiichi Kondo.

I had good contacts with Yoshio Kato, from Tosoh Biosciences formerly Toyo. Soda Manufacturing Co in Yamagu, chi Japan With Yoshio I explored the. island of Kiushi south of Yamaguchi, Barry Karger and I were invited as.
guests at the 50th anniversary of Tosoh, in Osaka In 2000 I was awarded a. fellowship by the Japan Society for the, Promotion of Science My job was to. give approximately 10 lectures at Japa, nese universities I began at Chiba Uni. versity in the vicinity of Tokyo went, south to Toyohashi and Nagoya spent. two weeks at Kyoto and finally visited, Shigeru Terabe at Himeji University I.

Pharmacia became a major sponsor the, organization of the meeting was handed. over to Bengt sterlund of Pharmacia, who had a background as a biochemist. Bengt managed both ISPPP meetings, the one in the United States and the. one in Europe until Pharmacia stepped, out The rest of the story one can read. in a special report entitled ISPPP, The successful route to biopolymer sepa.

Milton T W Hearn and Klaus K Unger Chromatography Down Under. My first encounter with Milton T W, Hearn dates back to the early 1980s. Milton is a renowned biochemist in the, department of biochemistry of Monash. University in Melbourne Australia, His special fields are peptide syntheses. and purification protein chemistry and, analysis and downstream processing.
He is the editor of a number of books, on these subjects. Milton became highly interested in, our work on the development of novel. stationary phases for peptide and pro, tein separations and we decided on a. close collaboration in early 1980 Birger, Anspach was the first Ph D student to. spend several years in Milton s group, before he returned to the National Insti.
