Two New Chromatography Organizations Formed
How to switch HPLC columns using valves. Different analyses sometimes use different columns. But even when the same column can handle more than one kind of sample, many chemists dedicate a column to each analysis. This prolongs column life, reduces interferences, and eliminates equilibration delays. Rheodyne's Technical Notes 4 tells how to use switching valves to connect as many as five columns to a chromatograph. Any column can be selected, while the off-line columns remain sealed at each end. The effect on resolution is shown to be negligible in most cases.

In two moves that will aid greater interaction and communication between chromatographers, a chromatography subdivision has been established within the American Chemical Society's Division of Analytical Chemistry and a number of chromatography discussion groups have agreed to organize into a federation. A motion adopted by the Executive Committee of the ACS Division of Analytical Chemistry at this spring's ACS national meeting in Seattle approved formation of a Subdivision of Chromatography and Separation Chemistry, to be probationary for three years. According to Charles H. Lochmuller of Duke University, chairman-elect of the Division of Analytical Chemistry, the main function of the subdivision will be to help the division's scientific programming committee develop chromatography symposia for national meetings. Other subdivision objectives include the establishment of improved chromatography educational programs and promotion of a greater level of overall interest and participation in the field of chromatography. Chairman of the new subdivision is Satinder Ahuja of Ciba-Geigy. Ahuja was a driving force behind the effort to obtain approval for the chromatography subdivision in the 2V2 years in which its formation was debated by members of the division. In addition to Ahuja, two other officers have been appointed: Clifford G. Scott of Hoffmann-La Roche is chairman-elect, and John G. Nikelly of the Philadelphia College of Pharmacy and Science is secretary of the new subdivision. The expectation is that establishment of the chromatography subdivision will increase division membership, since large numbers of chromatographers are not now members of the Division of Analytical Chemistry.

ACS members may join the new subdivision by sending a note with their ACS mailing address to Roland F. Hirsch, Secretary, ACS Division of Analytical Chemistry, Chemistry Department, Seton Hall University, South Orange, N.J. 07079. For those who are already members of the Division of Analytical Chemistry, there is no additional dues charge for membership in the Subdivision of Chromatography and Separation Chemistry. In a related development, a federation of chromatography discussion groups was recently established at an organizational meeting held at the 1983 Pittsburgh Conference. The prospect of such a development was discussed in an article in the February issue of A N A L Y T I C A L C H E M I S T R Y
(1983, 55, 253-54 A). According to Joseph L. Glajch (E. I. du Pont de Nemours & Co.) of the Delaware Valley Chromatography Forum, the first priority of the federation is to "get different chromatography discussion groups talking to each other and to start some ideas flowing on how different groups handle their programs." Through the federation, chromatography groups will cooperate on technical symposia at regional, national, and international meetings. The federation will also serve as a focal point for contacts with chromatography groups in other countries. The Delaware Valley Chromatography Forum will serve as a clearinghouse for the new group until a more permanent structure is decided on. Members of the federation plan to meet again at the 1984 Pittsburgh Conference in Atlantic City, N.J. For further information on the federation, contact Joseph L. Glajch, E.
