摘要：

A new thermospray vaporizer using direct electrical heating of a stainless steel capillary tube has been developed. This new vaporizer is powered by a feedback controlled triac power supply and provides both improved performance and better stability than previous thermospray interfaces. The theoretical background for the improved thermospray system is presented together with results of recent experimental studies on the effects on performance of various operating parameters.
