Background ICP stands for inductively coupled plasma discharge which duringthe past decade has become the leading spectrochemi- cal excitation source for atomic emission spectroscopy.ICP discharges also are applied commercially as an ion source for mass spectrometry and as an atom and ion cell in atomic fluo- rescence spectrometry. The popularity of this source and the need to collect in a single literature reference all of the pertinent data on ICP stimulated the publication of the ICP INFOR- MATION NEWSLETTER in 1975. Other popular plasma sources i.e. microwave induced plasmas direct current plasmas and glow discharges also are included in the scope of the ICP IN- FO RMA TI0 N NEWSLETTER. Scope As the only authoritative monthly journal of its type the ICP INFORMATION NEWSLETTER is read in more than 40 coun- tries by scientists actively applying or planning to use the ICP or other types of plasma spectroscopy.For the novice in the field the ICP INFORMATION NEWSLETTER provides a concise and systematic source of information and background material needed forthe selection of instrumentation or the development of methodology. For the experienced scientist i t offers a sin- gle-source reference to current developments and literature. Editorial The ICP INFORMATION NEWSLETTER is edited by Dr. Ramon M Barnes Professor of Chemistry University of Mas- sachusetts at Amherst with the assistance of a 20-member Board of National Correspondents composed of leading plasma spectroscopists. The Board members from around the world report news viewpoints and developments. Dr. Barnes has been conducting plasma research on ICP and other dis- charges since 1968.He also serves as chairman of the Winter Conference on Plasma Spectrochernistry sponsored by the ICP INFORMATION NEWSLETTER. Regular Features .Original submitted and invited research articles by ICP and *Complete bibliography of all major ICP publications. eAbstracts of all ICP papers presented at major US and inter- .First-hand accounts of world-wide ICP developments. especial reports on dcp microwave glow discharge and other *Calendar and advanced programs of plasma meetings. *Technical translations and reprints of critical foreign-lan- guage ICP papers. *Critical reviews of plasma-related books and software. Conference Activities The ICP INFORMATION NEWSLETTER has sponsored seven international meetings on developments in atomic plasma spectrochemical analysis since 1980 in San Juan Orlando San Diego St.Petersburg and Kailua-Kona. Meeting pro- ceedings have appeared as Developments in Atomic Plasma Specfrochemical Analysis (Wiley) Plasma Spectrochemistry ,and Plasma Spectrochemistry 11-IV (Pergamon Press) as well as in special issues of Spectrochimica Acta Part 5 and Journal of Analytical Atomic Spectrometry. The 1994 Winter Confer- ence on Plasma Spectrochemistry will be held in San Diego California January 10 - 15 1994; its proceedings will be published by Fall 1994. Subscription Information Subscriptions are available for 12 issues on either an annual or volume basis. The first issue of each volume begins in June and the last issue is published in May. For example Volume 18 runsfrom June 1992 through May 1993.Back issues beginning with Volume 1 May 1975 also are available.
