提出一种新的微量进样系统——微型电热蒸发与浓硫酸去溶联用系统,与传统的冷凝法去溶系统比较,新系统脱水完全,改进了M1P的稳定性和激发能力,是一种适合于MIPAES的实用型进样系统.研究了用该进样系统时Ar MIP和He MIP的光谱分析特性及易电离元素的影响.
A new micro-injection system-micro electrothermal evaporation combined with concentrated sulfuric acid desolvation system was proposed. Compared with the traditional condensate desolvation system, the new system was completely dehydrated and the stability and excitation ability of M1P were improved A Practical Injection System Suitable for MIPAES The spectral analysis of Ar MIP and He MIP and the influence of ionizing elements were investigated.
