Abstract

A commercial hollow cathode lamp is used as an atom reservoir for the atomic fluorescence of lead excited by a copper laser pumped dye laser. The glow discharge source is nearly an ideal atom cell for such measurements, having very low background emission and excellent atomization characteristics. A detection limit of 1.8 ag of lead within the laser beam is easily obtained.
