	abstract = "The photovoltaic method for the detection of liquid-phase photoionization in the absence of an applied electric field is compared to the traditional photoconductive method. Each system is characterized by means of signal and signal-to-noise ratio measurements with respect to laser pulse energy, applied voltage, electrode separation distance, solute concentration, and solvent composition. Although both techniques exhibit similar detection limits (1 &#215; 10<SUP>-7</SUP> M) for solutes in polar solvents such as methanol and water, the photovoltaic technique has a more extensive linear dynamic range (10<SUP>3</SUP>). Moreover, this technique allows detection of solutes in ionic solutions with comparable detectability and linearity.",
