Abstract

Four types of atomization chambers for atomic absorption are reviewed. Advantages and dis-advantages of each are considered. The effects of chamber dimensions and sample introduction system are considered in relation to accuracy, sensitivity, and convenience. Relative sensitivity is more significant for real samples than absolute sensitivity. When peak heights are measured, the relative sensitivity is proportional to the atomizer chamber length. When peak area is measured, the relative sensitivity is proportional to the third power of the atomizer chamber length. Matrix materials in general affect the accuracy of determinations by changing the rate or time of atomization. Matrix effects are less serious with long tight tubes than they are for tubes with openings near the center.
