| Abstract: | A small high irradiance laser ablation and ionization time-of-flight mass spectrometer with orthogonal sample introduction was described. Nearly uniform relative sensitivity coefficients as well as satisfactory resolving power(~2200) were achieved for most of metal elements. Fairly good signal stability was obtained by automated step moving of the sample stage in short time intervals. Interferences of multiply charged ions and polyatomic ions were nearly eliminated in the spectrum by utilizing helium as the... |
