我问的是：冷锥接口（cooled-cone）专利技术,起什么作用？
不是问ICP-MS上有没有的问题

来张图片

Vista’s Cooled Cone Interface (CCI) efficiently removes the cool plasma tail (the red zone, top) from the optical path.

This minimizes self-absorption and recombination interferences to provide a wide linear dynamic range and low background for the best detection limits.

Other designs,such as the shear gas approach (bottom),do not fully eliminate this zone, requiring excessive and expensive gas consumption (up to 20 L/min) for UV wavelengths.

不错来张图还是比较形象的

这个贴子可以结了，你说呢田兄？

我的问题基本上得到解决很感谢大家参与讨论，

有没有朋友谈谈气体切割尾焰的,效果怎么样

应当是不错的，要不然就不会形成商品的
