This Lumina™ hollow cathode lamp is the tellurium light source for the AAnalyst® 200, 300, 400, 600, 700 and 800 and PinAAcle® 500, 900F, 900H, 900T and 900Z atomic absorption spectrometers. A hollow cathode containing tellurium 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 tellurium atoms from the cathode and excite them, and the lamp emits the tellurium line spectrum.
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 tellurium, 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 tellurium spectrum for two years or 5,000 milliampere-hours, from the date of shipment.
- For higher intensity and lower detection limits the System 2 electrodeless discharge lamp for tellurium is N3050680, used with EDL driver 03030997
- Tellurium is also available in the multi-element Lumina lamps N3050206 (Sn/Te); multi-element lamps are for flame use only
- Non-coded 9-pin Intensitron lamps fit PinAAcle and AAnalyst instruments with the plug adapter N3050197
