Rapid on-line preconcentration and suppressed micro-bore ion chromatography of part per trillion levels of perchlorate in rainwater samples.


The development of a rapid method for the determination of perchlorate in rain and drinking waters is presented. In the optimised method, an on-line preconcentration technique was employed utilising a 10 mm x 4.6 mm Phenomenex Onyx monolithic guard cartridge coated with (N-dodecyl-N,N-dimethylammonio)undecanoate for selective preconcentration, with… (More)
