This Lumina™ hollow cathode lamp is the manganese light source for the PinAAcle® 500, 900F, 900H, 900T and 900Z atomic absorption spectrometers. A hollow cathode containing manganese 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 manganese atoms from the cathode and excite them, and the lamp emits the manganese line spectrum. Manganese is determined at its 279.48 nm resonance line in an air-acetylene flame.
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 manganese, 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 manganese spectrum for two years or 5,000 milliampere-hours, from the date of shipment.
- Manganese is also available in the multi-element Lumina lamps N3050212 (Cu/Fe/Mn/Zn, quartz window), N3050214 (Co/Cr/Cu/Mn/Ni), N3050215 (Co/Cu/Fe/Mn/Mo), N3050217 (Co/Cr/Cu/Fe/Mn/Ni); multi-element lamps are for flame use only
- Non-coded 9-pin Intensitron lamps fit PinAAcle and AAnalyst instruments with the plug adapter N3050197
