A carbon wire amperometric flow through detector is described which is easily constructed at low cost for application to flow injection analysis,continuous stream analysis and liquid chromatography.The theoretical limiting current of the detector is 2.14×10⁶nCD^2/3u_f^1/3 with 36% actual current efficiency.By use of flow injection analysis,thedetecting limits for Ag(I) and Cr(VI) had achieved 1 ppb and 0.4 ppb respectively with 1.2% (n=20) relative standard deviation after preliminary experiments.
