This Lumina™ hollow cathode lamp is the aluminum light source for the PinAAcle® 500, 900F, 900H, 900T and 900Z atomic absorption spectrometers. A hollow cathode containing aluminum and an anode are sealed in a 2 in. (50 mm) diameter glass envelope filled with inert gas. An electrical potential between anode and cathode ionizes the fill gas; the ions sputter aluminum atoms from the cathode and excite them, and the lamp emits the aluminum line spectrum. Aluminum is determined at its 309.27 nm resonance line in a nitrous oxide-acetylene flame or in the graphite furnace.
Lumina lamps are built with a larger internal volume than conventional hollow cathode lamps, so a greater supply of fill gas is available at optimum pressure and the lamp lasts longer. The lamp is coded: when it is slid into the lamp mount or turret of a PinAAcle or AAnalyst™ instrument, the instrument reads the code and sets the wavelength, slit and lamp current for aluminum, and on PinAAcle instruments with Syngistix™ software the lamp’s operating hours are recorded automatically. It is supplied without a cable; earlier PerkinElmer AA spectrometers without code reading use it with the Intensitron® adapter cable.
The lamp is warranted to meet its intensity and absorption specifications for six months or 5,000 milliampere-hours, and to light and emit the aluminum spectrum for two years or 5,000 milliampere-hours, from the date of shipment.
- Aluminum is also available in the multi-element Lumina lamps N3050207 (Al/Ca/Mg), N3050211 (Al/Cu/Fe/Ti), N3050216 (Ag/Al/Cr/Cu/Fe/Mg, quartz window), N3050218 (Al/Ca/Cu/Fe/Mg/Si/Zn, quartz window); multi-element lamps are for flame use only
- Non-coded 9-pin Intensitron lamps fit PinAAcle and AAnalyst instruments with the plug adapter N3050197
