To attain this objective, a rapid and sensitive reversed phase high performance liquid chromato-
graphic (RP-HPLC) method has been developed and validated according to the guidelines of FDA, ICH and USP with respect to accuracy, precision, specificity and linearity.
Perchlorate concentration was analyzed using a Metrohm-861 Advanced Compact ion chromato-
graphy equipped with a Metrosep A Supp 5 (250x4 mm) analytical separation column, a Metrosep RP Guard column, and a detection stabilizer (providing a temperature of 35 degC).
Blood, urine, ashed bones samples, dried in quartz ampules, sealed and irradiated in a reactor, 233Pa, the cooled irradiated samples were cleaned by multiple column chromato-
graphy, solvent extraction and evaporated on counting planchettes [87, 89].
