Optimizing your ICP Sample Introduction System for
Improved Analysis of Oils and Organic Solvents
While ICP-OES technology has undergone considerable developments on the spectrometer
side, challenges related to the sample matrix still remain. For example, oil analysis by
ICP can be challenging due to the use of volatile organic solvents that typically results
in plasma instability. Additionally, when organic solvents are introduced into the plasma,
the temperature gradient along the axis of the ICP torch increases significantly, which
can lead to premature failure of the standard quartz ICP torch. Oil analysis also often
requires labor intensive sample preparation with volatile organic solvents. In this paper we
will present sample introduction components specifically designed to optimize your ICP
sample introduction system for improved oil and organic solvent analysis.
Nebulizer Selection
When dealing with oil analysis or an organic solvent, the first component you should select
is a proper nebulizer. The Glass Expansion website features a very helpful nebulizer
selection guide that will help you to arrive at a proper selection, including a new smart
phone app (Figure 1).
