Comparison of two pneumatic nebulizers for use in ICP emission spectroscopy

摘要: The connexions between aerosol gas flow and optimal observation height were experimentally illustrated by comparing two pneumatic nebulizers. If we succeed in getting a higher sample with lower velocity, the remaining time of plasma flame will be considerably prolonged. This results maximum emission all elements studied up to now at lowest possible flame. Thus an essential supposition for simultaneous multielement analysis is fulfilled: A correction single element measurements does not cause improvement, can firmly installed optical axis. detection limits are improved prolonged time. reproducibility ≤ 1% concentration range 10 ng/ml.
