Abstract
A graphite tube assembly for use in the atomic absorption spectroscopic measurement of samples, particularly liquid samples, during the passage of a beam of radiation through a graphite tube is disclosed. The graphite tube assembly includes a graphite tube and a sample holding platform which are cooperatively adapted to allow the platform to be removed and reinserted, or exchanged with another platform, while maintaining a preselected orientation of the platform with respect to an inlet port extending through the wall of the graphite tube.
Claims6
A graphite tube assembly for use in an atomic absorption spectrometer comprising:
- a graphite tube adapted to permit a radiation beam to be transmitted therethrough, said tube having an inlet port extending through a wall thereof;
- and
- a sample holding platform having a recess in one surface thereof for retaining a sample material to be tested, said sample holding platform being adapted to be disposed within said graphite tube external of said beam path, said platform and said tube having, cooperatively mating surfaces for locating said platform at a preselected orientation within said tube whereby said platform can be removed and reinserted, or exchanged with another similarly shaped platform, to said preselected orientation.
