The Model 63 Carbon Rod Atomizer is the latest practical development in flameless atomic absorption spectroscopy. It has outstanding advantages over conventional flame techniques — particularly in clinical and pollution areas.
•sensitivity and detection limits are considerably
better than those obtained by orthodox flame methods
•sample volume requirement — the Model 63 can handle
any sample volume between 0.5 μ\ and 20 μ\
•little or no sample preparation — for example, with
whole blood all you need is a syringe and a .5 μ\ sample
•simple aqueous standards can be employed for most
analyses
•two types of atomizer (cup or tube) for flexibility and
analytical versatility I I solid sample capability
•simple determinations on air-borne particulate
material
•ready interchange of cups and tubes allows high-speed
analytical routines for batch processing of samples
•inter-element interferences either eliminated or strictly
controlled The Model 63 solves many analytical problems in clinical chemistry, agriculture, metallurgy, water analysis, foodstuffs, petroleum products, toxological studies, quality control.
