FIELD: chemistry.
SUBSTANCE: formation water sample under analysis is separated from oil, cleaned from mechanical impurities, clarified in a centrifuge and dissolved volatile nonpolar compounds which hinder quantitative determination of isopropanol are extracted with hexane.
EFFECT: removing volatile nonpolar substances dissolved in formation water which hinder gas chromatographic determination of isopropanol.
