Abstract: The design and application of capillary flow cell optimized for laser induced photoacoustic spectroscopic detection of effluent are described. The characteristics arid analytical figures of merit of the flow cell are presented. Application of the flow cell to the detection of Co2+ effluent is demonstrated. The detection limit of Co2+ corresponds to 2×10-6 cm-1 in absorptivity for LIPAS detection.
