Torches and methods of using them

摘要

Certain embodiments described herein are directed to a torch that includes a lanthanide or actinide material. In some embodiments, the torch can include one or more other materials in combination with the lanthanide or actinide material. In some embodiments, the torch can comprise cerium, terbium or thorium. In other embodiments, the torch can comprise a lanthanide or actinide material comprising a melting point higher than the melting point of quartz.

主权项

1. A torch comprising an outer tube configured to sustain an atomization source in the outer tube, the torch outer tube comprising an inlet end within a first section of the torch outer tube and an exit end within a second section of the torch outer tube, in which the torch is configured to desolvate sample at the first section of the torch outer tube and to sustain an atomization source within the second section of the torch outer tube, in which the first section and the second section of the torch outer tube are coupled to each other through at least one material, in which the first section of the torch outer tube comprises a non-refractory material, and in which the exit end of the outer tube comprises at least one lanthanide or actinide material, and in which the material coupling the first section and the second section is different than the non-refractory material of the first section and the at least one lanthanide or actinide material of the exit end of the outer tube.
