The only thing variable about the SF 770 Spectroflow Monitor for liquid chromatography ...is the wavelength!
• It consistently offers highest sensitivity with low noise and baseline drift. • It classically follows Beer's law in its measurements. • It routinely includes an automatic gain control and zero suppression. • It equally interfaces with all Liquid Chromatography systems. • It inconspicuously takes up very little room. • It uniquely incorporates a doublebeam design. • It invariably is an honest instrument, not relying on gimmicks to achieve unrealistic specs. • It indubitably is preferred by more liquid chromatographers than all other models combined.

A w a r d s totaling $4200 are being offered to U.S. and Canadian authors of papers on applications and t e c h niques of electrofocusing in biochemistry by L K B Instruments, Inc., a company specializing in the developm e n t of instruments for electrofocusing. T h e awards will be presented a t E L E C T R O F O C U S / 7 8 , which is being organized by the company. Anyone wishing to enter the contest is invited to submit original research papers not later t h a n May 10, 1978. For more information contact: J. Ball, L K B Instruments, Inc., 12221 Parklawn Dr., Rockville, Md. 20852, 301-882-2510. Marcel D e k k e r , Inc., t h e New York City-based publisher of scientific literature, has initiated t w o n e w scholarly journals—Journal of Liquid Chromatography and Drug and Chemical Toxicology. T h e former, edited by Jack Cazes of Waters Associates, Milford, Mass., will be p u b lished every two months, six issues per volume for $48 per volume. T h e p u b lisher promises to provide a forum for all phases of liquid chromatography from analytical and preparative articles to papers dealing with liquid chromatography as a science in itself. Papers in thin-layer chromatography and all modes of liquid column chromatography will also be welcomed. T h e first issue published in J a n u a r y 1978 contains eight papers.
