1 iroday, 2 Tomorrow Atomic Absorption with an ADD-vantage Take advantage of IL's all new Model 253 Atomic Absorption/Emission Spectrophotometer. A revolutionary single channel, double beam, digital readout instrument the IL 253 w a s specifically designed for optimum performance, stability and easy expansion into a dual double beam unit. Start with the basic IL 253. It is economically priced. Then a s your analytical n e e d s grow, simply add plug-in components to make your job easier. Add a turret for faster multi-element analyses. Or if you're working with high solids add Background Correction. This feature, plus the well known advantage of double beam, will greatly e n h a n c e the accuracy of your answers. As your workload increases, add a
complete second double beam channel to the IL 253. It's quick and easy. Just plug in six components. No outside boxes, each addition is an integral part of the unit. Then analyze samples for two elements simultaneously by absorption a n d / o r emission on either channel. Or, for the highest possible precision use the new channel a s an internal standard. The IL 253 provides all this and a great deal more at a cost no higher than s o m e single beam, meter readout, economy model instruments. For instance, you get such well established IL features a s the only
IL
standard AA monochromator fitted with step-variable curved slits; the patented Counter-Flo Jet T for greatly increased efficiency of nebulization, plus automatic ignition with "fail-safe" circuitry. Best of all the IL 253's innovative design eliminates the need to buy an expensive second unit to handle increased demands. It provides the highest sensitivity, precision and stability in a single channel, dual beam absorption/emission spectrophotometer available, plus the unique "Two Tomorrow ADD-vantage."
