title: Assay of In Vivo Chromium with a Hollow-fiber Dialysis Sensor.
abstract: The analytical in vivo chromium ion was searched for using a voltammetric hollow-fiber dialysis sensor via square wave stripping voltammetry (SW) , cyclic voltammetry (CV) , and chronoamperometry. Under optimum parameters, the analytical results indicated linear working ranges of 50~400 mg/l CV and 10~80 μg/l SW within a 30-sec accumulation time. The analytical detection limit (S/N) was 6.0 μg/l. The developed method can be applied to in vivo tissues and in ex vivo toxicity assay, as well as to other materials that require chromium analysis.
