The atomic absorption spectrophotometer with built-in non-obsolescence
When we built the TECHTRON AA-4, we made sure that it would be around for a long time. We did this by designing it to permit future updating at minimum cost. This "modular" technique insures ease of operation and simplifies routine maintenance and service. Modular design has also made possible such construction features as an optical rail and open sample compartment. These allow for rapid adaption to such special sampling devices as graphite or RF furnaces, absorption tubes and total consumption burners of all types. SPEED, SENSITIVITY. The AA-4 is a highly versatile instrument which gives the researcher the pinpoint accuracy he needs yet allows the industrial chemist to use it quickly and economically for quality control. It provides rapid analysis of routine samples in fields such as food and beverage man-
ufacturing, petroleum products, and mining and metallurgical processes. And it measures with sensitivities of from ppb to ppm for applications including pharmaceutical analyses, pollution control and clinical medicine. If you'd like to see and test the TECHTRON AA-4 firsthand, just ask us. We'll arrange for a demonstration in your lab. FREE RESONANCE LINE PLAQUE. A 2&''x 5 "aluminum plaque
containing the major resonance lines for 66 elements measured by AA is yours for the asking. It attaches right to your spectrophotometer. For the plaque and Data File C802-48 containing AA-4 literature, write Cary Instruments, 2724 South Peck Road, Monrovia, California 91016.
