| 摘要 | The traditional Carius tube technique is cumbersome and requires skilful work to seal the Carius tube, which can be used only once. We describe a modification to the technique that does not require the use of a high-temperature welding torch to melt the Carius tube to seal it. The newly designed Carius tube consists of a main body with a 3 mm-thick glass wall, a neck and head with walls 4 mm in thickness, and an efficient screw-thread stopper. These new features allowed the tube to be used repeatedly. We demonstrate relatively low procedural blanks derived for Re and Os, and platinum-group elements (PGEs), using the redesigned tube. A temperature of 220 degrees C could be reached for about 5 ml of HNO3 for a 47 ml tube and for 32 ml of inverse aqua regia for a 200 ml tube. This digestion technique can be used for routine analysis of Re and PGEs in geological samples. |
