Study on a novel circulating cooling solid-phase microextraction method
Journal of Chromatography A, 1135(2006)1-5，-0001，（）：
A novel solid-phase microextraction (SPME) setup, circulating cooling solid-phase microextraction (CC-SPME), is developed for determining organochlorine pesticides (OCPs) in water. The linearity area of this method is 0.5-120g/l, its RSD value is less than 10% and detection limit is in the low ng/l when it is used to detect-hexachlorocyclohexane, which is better than traditional headspace SPME (HS-SPME) and direct immersion SPME (DI-SPME) methods. The influence of factors such as pH, ionic intensity, adsorption time, and adsorption temperature were also investigated, respectively.
