| Popis: | The usefulness of cross-excitation by electric discharge to intensify spectral emission from plasmas generated by a laser micorprobe was extended to a sampling resolution of 10–25 μ without burning the peripheral zone. This proved practical for sampling single biological cells for elemental analysis. It was accomplished by modifications in shape of the carbon electrode tips, their positioning, and the amount of spark energy used in the cross-excitation. |
