英文摘要	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(similar to 2200) were achieved for most if 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 buffer gas in the ion source, which resulted In a relative clean background. Standardless semi-quantitative analysis of steel was realized and the limits of detection are about 10(-6) g/g for most of metal elements.
