摘要/Abstract

摘要： 报道了用于微波等离子体炬原子发射光谱仪（MPT-AES）的新型注射泵-超声雾化器联用进样系统，考察了影响该系统性能的因素. 分别用气动雾化进样系统和注射泵- 超声雾化联用进样系统进样，测定了Cd， Cu， Mg， Ca和Na等5种元素、浓度均为1×10 ^-4％的混合溶液. 结果表明, 注射泵-超声雾化联用进样系统所得的谱线强度是气动进样所得谱线强度的2～3倍，而超声雾化进样的检出限比气动雾化进样小2～10倍 , 且超声雾化进样系统的记忆效应较强，所需清洗时间较长.

Abstract: The feeding-sample system of MPT-AES is pneumatic nebulization syste m, but its efficiency is not good. A new-built injector pump-ultrasonic nebuli zer combination feeding-sample system has been designed. Its performance was te sted and compared with that of the pneumatic nebulization system. It can be conc luded that the new-built feeding-sample system can increase the spectral line intensity about 2～3 times and decrease the detection limit about 2～10 times. M oreover, this new-built system can reduce the time taken by washing the sample c ell from 30 min or so to about 10 min.

Key words: injector pump-ultrasonic nebulizer, MPT-AES, pneumatic nebulization system
