Use of Ion Chromatography Techniques in Aerosol Inorganic Ions Determination

The new progress of ion chromatography（IC）techniques in aerosol soluble inorganic ions deter mination is briefly reviewed in this article.The main advantages of IC over the classical analysis method are（a）less deter mination time,（b）less solvent waste and（c）high resolution.IC has become a pro minent sample analysis technique that conquers the weakness of chemical analysis method.Integration of IC with aerosol soluble inorganic ions deter mination is of great interest.This article discusses the principles of IC,component and operation of required instrumentation,as well as the important note of sampling and sample pretreatment, the select and effects of various factors of separating column and eluent,and the development of suppressor and detector using the technological process in aerosol soluble inorganic ions as main clue.
