✦ Synopsis

The effects of the cell structure on the mass detection limits in fluorimetric detection in micro high-performance liquid chromatography were examined. Scatter of the light by reflection or refraction from the cylindrical quartz cell wall increased the noise level. This type of scattered light could effectively be prevented from entering the photomultiplier by either tilting the flow cell or using appropriate cut-off filters. In fluorimetric detection in the presence of a packing material, scattered light from the surface of the packing material could be shut out by the latter method.
