A simple on-line fibre optics UV detector for microcolumn HPLC
- 16 Downloads
Modification of the UV absorbance detector for LC is described. It is based on a simple combination of a commercial photometer with optical fibres to conduct the light. The performance of the detector is illustrated by the analysis of polyaromatic hydrocarbons on a packed fused-silica column. The minimum detectable concentration for naphthalene was measured as 6·10−6M.
