We describe a laser ablation and ionization time-of-flight mass spectrometer with orthogonal sample introduction and axial field rf-only quadrupole cooling device. Experimental results have shown the fairly uniform sensitivities for different metal elements, and a satisfactory resolving power. Little interference is shown in the spectrum. The detection limits are about 10(-7) - 10(-8) g/g for most of the metal elements. (c) 2006 Published by Elsevier B.V.
