title: A simple method for improving control of the time constant in recording transient signals in atomic-absorption spectrometry.
abstract: Significant improvements can be made in signal:noise ratios of transient signals arising in atomic-absorption spectroscopy by the use of resistor-capacitor damping. A suitable device is described and the effect it has on signals arising from instruments using analogue and digital forms of output is demonstrated.
