摘要：

This work describes preliminary results of research devoted to the development of thermospray sample introduction systems that are capable of operating with liquid flow rates of 10 ml min-1, or more. This development involved the modification of a thermospray power supply to provide about 1 kW of power, and longer vaporizers to increase the residence time of the liquid stream within the heated portion of the system. Use of this system with ICP-AES resulted in sensitivity increases of about a factor of two, when sample flow rates were increased from 2 to 5 ml min-1. Prospects for further improvement are also described.
