Abstract
A highly sensitive analytical method for measuring bisphenol A (BPA) and 8 alkylphenols using high performance liquid chromatography (HPLC) with fluorometric detection has been developed. Detection limits improved by using both fluorometric detection and large volume injection.
Sensitivities of the compounds with fluorometric detection were ca. 20 times higher than those with UV detection. And the sensitivities with large volume injection up to 400ul increased 20 times higher than those with 20μl injection.
Method determination limit for BPA was 0.33 ng/m3 when sample was collected by 1l/min for 24hours. And it doesn't need preconcentration and/or derivatization techniques. This method can be applied to not only the survey of the ambient air but also indoor air. The method may be applicable to the survey of environmental water, too.
