Photoelectric Spectrometry Group

Abstract

AT a meeting held in Cambridge on July 16, 1948, the Photoelectric Spectrometry Group was formed with Dr. J. R. Edisoury, of the Research Department of Messrs. Leven, Bros., Port Sunlight, as chairman. Although originally conceived as a discussion group for users, ef the Beckman spectrophotometer, the scope was later widened to cover other instruments of sSnflar type. Among the activities envisaged were the holding of scientific meetings, the organising of collaborative tests, the maintenance of an accessories pool for the Beckman instrument, liaison with manufacturers of spectrophotometric equipment in Great Britain, and the publication of a bulletin. The first number of the Photoelectric Spectrometry Group Bulletin (obtainable from W. H. Storey, Hon. Sec. P.S.G., Unicam Instruments, Arbury Works, Cambridge ; pp. 16 ; price 5s.) was issued in April and contains papers by Dr. E. R. Holiday on “Adaptation of the Hilger Spekker Photometer and Medium Spectrograph for Photoelectric Work", Dr. G. H. Beaven on ”Notes on the Design, Operation and Maintenance of the Beckman Spectrophotometer"and Dr. J. R. Edisbury on “Relative Readings on Twenty-eight Beckman Spectrophotometers". Several notes on technique and accessories are also included. The Group has now completed its first year of operation and has held four well-attended scientific meetings, membership of the Group now standing at more than one hundred and thirty. The possibility of affiliation to one of the larger existing societies will be given consideration in due course.
