摘要：

The rapid-clearing spray chamber design utilizes two critical features for a rapid-clearing system-a nebulizer wash and a high-volume gas flush. The combination of these two features with supporting design features provides a system which can clear out a signal of Fe or Zn from 500 ppm to undetectable levels (below 10 ppb) in about 20 s. A tubular injector is used in the ICP torch to minimize plasma disturbance during the gas flush cycle. Several modifications to the spray chamber were necessary to handle the nebulizer wash efficiently.
