The resultant positively charged complexes were resolved by NACE using 2\u2010propanol\/acetone electrolytes prior to mass spectrometric detection using an Agilent<jats:sup>3D<\/jats:sup>CE system coupled to a Bruker Esquire 3000+ quadrupole IT mass detector. Using electrokinetic injection, the method detection limit for perchlorate in nonaqueous media was 10\u2005\u03bcg\/L.
