ABSTRACT

Ion chromatography is a powerful tool for oilfield water sample analysis. Replacement of the classic analytical methods leads to the use of smaller sample content, faster analysis and getting multiple information in a single analysis. In oil industry we can find numerous ion chromatography uses, some of which are connected to oil investigations and some to ecological demands and sustainable development. Oilfield waters are complex matrices with lots of artificial added substances and every sample demands specific approach. By combining anion separation and detection with proper sample preparation, determination of usual (F^–, Cl^–, NO^2-, NO^3-, Br^–, SO₄^2-,PO₄^3-) anions in oilfield water samples can be achieved.

Keywords: ion chromatography, oilfield water, anion analysis
