Automatic Sampling System Employing a Nebulizer for Solid-Surface Room-Temperature Phosphorescence Analysis

Abstract

A new experimental system for the automation of Solid-Surface Room Temperature Phosphorescence (SSRTP) has been constructed. Samples were sprayed onto a moving filter paper by means of a conventional atomic absorption nebulizer. A new sample holder, which permits measurements of a previously optimized position for a maximum phosphorescent signal, has been designed and adapted to the cell compartment of the spectrofluorimeter. The results show that a considerable step has been taken towards the automation of SSRTP and, therefore, to its application in areas where numerous samples are handled routinely.
