Ion-moderated partition chromatography
WebIon Exclusion Chromatography (IEC) finds application in the separation of a wide range of small, neutral or partially ionized molecules. In IEC, the strong as well as weak electrolytes are eluted unseparated, the first at the beginning and the latter at the end of the elution. The retention volumes of the remaining electrolytes are found to be proportional to their … WebAminex HPLC Columns Selection Guide. Wine Analysis with the NGC System.

Web4 apr. 2024 · Ion-exclusion chromatography is an excellent technique for determination of organic acids and weak retention anions based on the mechanism of Donnan exclusion, and no publication has been reported for determination of fluoride using ion-exclusion chromatography. Web1 jan. 1983 · This liquid chromatographic procedure overcomes many common limitations of trace-level gas chromatographic determinations of acetic acid such as peak ghosting, non-linear calibration, and inadequate detection limits.
WebIon-exclusion chromatography is defined [91] as a technique used to separate weak acids, amino acids, sugars, alcohols and other substances on an ion-exchange column. Because of Donnan exclusion, ionic material is excluded from the ion-exchange resin and passes quickly through the column.
