NEW PERKIN-ELMER Model 154-C VAPOR FRACTOMETER INCREASES THE ANALYTICAL REACH OF ANY LABORATORY An unprecedented column temperature range — from —78.5°C to 300°C—permits the Perkin-Elmer Model 154-C Vapor Fractometer to make clean separations of mixtures ranging from inert gases and light hydrocarbons to heavy oils, greases — and even solids. With its complete line of accessories, the Model 154-C gives you the broadest quantitative capability of any single-stage chromatographic instrument on the market. HERE'S W H A T THAT M E A N S TO Y O U :
Advanced design enables the Model 154-C to shoulder a bigger portion of your analysis work. For example, three new refrigerated columns for the 154-C let you handle rare gas studies, trace analyses of light gases, and checks of many industrial hydrocarbon mixes. On the other end of the scale, high temperature columns separate liquids — and solids — boiling u p to400°C. The higli sensitivity thermistor detector measures traces and major components with equal accuracy. Once set, column temperature varies only one-tenth of a degree C. Automatic control of peak attenuations keeps major components on scale—permits unattended operation. A copper oxide comhustor reduces complex hydrocarbons to easilv-measurcd CO-j and H-O — enhances detector sen-
sitivity and prevents fouling of detectors and vent lines. Find out how the Model 154-C can enlarge the scope of your research and development work. Write us at 780 Main Avenue, Norwalk, Conn.
