“…Alkalinised samples are loaded onto Extrelut column that is coupled on-line with PRS, and dichloromethane is passed [8,11,45,48,49,53,67,70,74,78,79,81,82,84,87,90,91,[95][96][97][98]102,107,[111][112][113] in order to extract HAAs and other basic organosoluble materials. PRS can retain other dichloromethane-soluble compounds, which may interfere with the HAAs during HPLC analysis.…”
