Shimadzu, 062-65055-05, Deuterium Lamp, AA, UV-Vis

The Shimadzu L6380 deuterium lamp is a replacement ultraviolet continuum light source for compatible atomic absorption instrumentation, including the AA-6300 series. A deuterium lamp supports background-correction measurements by providing a broad ultraviolet emission spectrum distinct from the element-specific hollow cathode lamp. Correct background measurement can improve confidence when a sample matrix contributes nonspecific optical absorption or scattering, provided the analytical method and instrument settings are appropriate. This replacement lamp is not an elemental hollow cathode lamp and does not replace the element-specific analytical source. Handle the lamp by its designated mounting surfaces, protect the optical window from contamination and follow the electrical isolation and lamp installation procedures for the instrument. After replacement, allow the required warm-up and verify optical energy, background-correction operation and performance with method blanks and standards. The AA-6300 service schedule identifies the deuterium lamp as a periodically replaced component; actual lamp life depends on operating conditions. Confirm compatibility for any other UV-Vis or atomic absorption model separately.
