Abstract
This paper describes a novel chromatographic detection method using an integrated electrical impedance spectroscopy particle detector fabricated using micromachining technologies for use in chemical and biological analysis systems such as liquid chromatography or field flow- fractionation systems. The design, theory, fabrication, and testing of the detector are described. Critical parameters of the detector such as detection limits, and the effects of flow rate and applied voltage on detector response are measured. Motivation for use of an on-chip impedance spectroscopy detector is given.
