新型ICP光源雾化器喷口的工艺讨论

雾化器是1CP光源重要组成部分,本文重点讨论气动玻璃同心雾化器两喷口截面积和研制工艺。ICP光源的检出限在很大程度上是由雾化器的性能决定的,雾化器的性能可用雾化效率来表示,即引进的样品溶液转化为气溶胶的百分数。根据国内外资料,雾化效率最高可达12—25%。1CP光源另一个影响检出限的因素是载气的流量。调节载气流量是做到气溶胶均匀喷射和提高雾化效率的一

A Discussion on Manufacturing Technique of New Nebulizer and Sealing of The Two Nozzlea Used for 1CP Source

The key points of pneumatic nebulizer are the area ratio of solution noz- zle to gas nozzle, concentricity and thin wall. Those factors effect the nebulize efficiency, sensitivity and precision directly. In this paper, the calculation me- thod of choosing diameters of tile two nozzles of nebulizer, techniques for making thin-wall capillary and sealing two nozzles concentriclly and other factors effecting the precision were described.
