Our new HPLJC
Columns ore well pocked!
•
Guaranteed peak symmetry and minimum plates per meter doubly assure you of optimum column performance. A completely new line of "stateof the-art" packed columns for high pressure liquid chromatography is now available in the U.S. and Canada from Rheodyne. All columns are 4.6 mm ID χ 25 cm long. Each column is tested and supplied with its own chromatogram. Currently six columns are available over a price range of $180 to $240. The table below showing column performance specifications and typical test conditions offers an excellent argument for the addition of these columns to your HPLC equipment. COLUMN TYPE

For Your Information An annotated bibliography on glucose methodology, the second in a series, is available free of charge from the Center for Disease Control. The bibliographies are being prepared in parallel with the development of reference methods to make a comprehensive survey of the literature available to those with an interest in a particular analyte for which a reference method is being developed. This bibliography contains 905 annotations, from 1841 through March 1976, arranged chronologically by year and alphabetically by author within each year. Copies of the uric acid bibliography published in 1974 are also available free of charge. Requests should be addressed to Technical Information Service, Clinical Chemistry Division, Center for Disease Control, 30Cham, Atlanta, Ga. 30333. The Perkin-Elmer Corp. and Physical Electronics Industries, Inc., have entered into an agreement in principle to merge the two companies subject to the approval by the board of directors of the respective companies. Physical Electronics Industries, headquartered in Eden Prairie, Minn., is a leading producer of Auger and ESCA spectroscopy instrumentation for surface analysis. PerkinElmer, headquartered in Norwalk, Conn., produces analytical and other scientific instrumentation, small- and medium-scale data systems, and metallurgical coating equipment. The sales of medical electronic laboratory instruments in the U.S. have grown from $90 million in 1969 to $263 million in 1976 and are expected to reach nearly $440 million by 1980, according to a study on clinical laboratory instrumentation.
