A new type of Zeeman-effect atomic-absorption spectrophotometer.
A new type of Zeeman-effect atomic-absorption spectrophotometer has been developed. It uses fast heating of a special atomizer made from a pyro-coated graphite tube lined with tungsten-tantalum alloy, for easier determination of refractory and rare-earth elements. A boxcar integrator is used, and the atomic absorption, background absorption and atomization temperature can be recorded. By means of the Zeeman effect, the instrument can correct for background absorbance up to 2.0.
