用ICP-AES法分析样品时,多数样品为溶液。处理难溶样品费时多、易沾污。有时还需加入大量试剂,使得空白或背景增大,影响分析灵敏度和检测能力。有人研究将固体粉末样品或含有固体颗粒的悬浮体直接引入ICP的分析方法。Fry及Denton用原始的Babington雾化器将悬浮体样品引入原子吸收;Sugimae和Mizoguchi利用V型槽Babing-ton型雾化器分析空气飘尘颗粒物质;Mc Kinnon等人设计了一种改进的Babington型雾化器-GMK雾化器;Broekaert等人用GMK雾化器分析粉末悬浮体样品。本文对GMK雾
When analyzing samples by ICP-AES, most samples are solutions. Time-consuming treatment of insoluble samples, easy to stain. Sometimes need to add a large number of reagents, making the blank or background increases, affecting the analysis sensitivity and detection capabilities. Analytical methods for direct introduction of solid powder samples or suspensions containing solid particles into ICP have been studied. Fry and Denton introduced the sample of the suspension into the atomic absorption using the original Babington nebulizer; Sugimae and Mizoguchi analyzed airborne particulate matter using a V-groove Babington tonometer; Mc Kinnon et al. Designed an improved Babington-type Nebulizer - GMK Nebulizer; Broekaert et al. Analyzed powder suspension samples with a GMK nebulizer. This article on GMK fog
