Sample preparation in ion-chromatography

Abstract: lon-chromatography, a relatively new technique in a nal yti cal chemistry, has already shown great promise toward solving complex trace analysis problems, in particular the speciat ion and quantitation of allion~. It is especially attractive to the fi e ld of microanalysis. The method of sample preparation, however, is (Tucial in order to realize this capac it y. Existing microanalytical methods nearly always must be modified to be compatible with ion-chrof~latugraphy, and often, more extensive sample cleanu p… Show more

“…Also, several species can be detected simultaneously. 20 For chemical analysis, we prepared three different perovskite films composed of CH 3 were heated for about 5 min while the mixed-halide sample was heated for 45 min. As the CH 3 NH 3 PbI 3 and CH 3 NH 3 PbCl 3 samples were prepared only for determining the position of the Cl ¹ peak in ion-chromatographic analysis, the conditions followed for fabrication were not optimized, as done for CH 3 NH 3 PbI 3¹x Cl x (350 nm).…”

“…The amount of reacted chloride in the Merrifield resin was estimated by the ion chromatography method (Table S1). 23,27 The structure of 8 was confirmed by comparing its IR spectrum with that of the model compound (Figure S4). 27 The following hydrolysis of 8 with hot hydrochloric acid in dioxane successfully afforded the desired GARI (9).…”

“…The decomposition technique must employ a reagent which either does not interfere with the chromatography or can be removed prior to injection. Popular sample-decomposition techniques, such as wet ashing with strong acids, are not suitable because the anion which is introduced into the sample at high concentration severely interferes with the chromatographic process (4).…”
