This is one of your two best buys in AA. Here's why:
Only Perkin-Elmer offers you the two most cost-efficient choices for your atomic absorption budget. One is the double-beam Model 2380 shown here. The other is its single-beam counterpart, the Model 2280. The most in microprocessor convenience These two instruments combine a powerful optical system with unmatched microprocessor convenience and flexibility. In fact, no other instrument in their price range offers all these features: automatic calibration with three standards; recalibration with a single keystroke; and automatic averaging of readings with coefficient of variation and standard deviation. You get the whole package whether you use the
instruments for flame AA, flame emission, or graphite furnace AA where you can measure peak height or peak area. A new burner system: better performance with any element or any sample The new burner system accommodates an impact bead. Result: improved sensitivity and detection limits for air/acetylene elements. Replacing the bead with a flow spoiler maintains high precision for elements requiring an N20/acetylene flame. You'll be able to analyze solutions containing high dissolved solids or solutions that may otherwise corrode the impact bead and cause contamination problems. This new burner system is also available for all other Perkin-Elmer AA instruments.
Plus: all our AA accessories With both these AA spectrophotometers, you can use the full range of Perkin-Elmer AA accessories, which include microcomputer-controlled graphite furnaces, microcomputer-controlled autosamplers for flame and HGA, two mercury-hydride systems, electrodeless discharge lamps and Intensitron® hollow cathode lamps. If you're looking for big AA capability at minimum prices, send for our literature on these remarkable new AA spectrophotometers. Write Perkin-Elmer Corp., Main Ave., MS-12, Norwalk, CT06856.
