Lead (Pb) System 2 Electrodeless Discharge Lamp

This System 2 EDL is the lead light source for the AAnalyst^® 200, 300, 400, 600, 700 and 800 and PinAAcle^® 500, 900F, 900H, 900T and 900Z atomic absorption spectrometers. Lead, or a salt of lead, is sealed in a quartz bulb containing an inert gas; when the RF field from the driver is applied, the gas ionizes and the coupled energy vaporizes and excites the lead, which emits its characteristic spectrum. An EDL is much brighter than a hollow cathode lamp at the lead resonance line of 283.31 nm, which gives better precision and lower detection limits for elements whose hollow cathode emission is weak. PerkinElmer uses this lamp for lead in graphite furnace work, for example in its edible oils and tea methods on the PinAAcle 900T at 283.31 nm and 0.7 nm slit, run at 440 mA in the tea method.

The lamp sleeve holds the pre-aligned bulb and has the same outside dimensions as a PerkinElmer 2 in. hollow cathode lamp, so it fits the same lamp mounts and turrets, and the coded adapter lets instruments with an automated turret set up the lamp automatically. It is used with a System 2 EDL driver, which connects to the RF power supply built into every PinAAcle instrument; one driver is needed for each lamp position in which an EDL is run. A locking pin on the driver prevents operation unless the sleeve is correctly installed.

The lamp is warranted to meet its intensity and absorption specifications for six months or 500 hours of operation, and to light and emit the lead spectrum for two years or 1,000 hours, from the date of shipment.

• EDL driver for PinAAcle and other instruments with a built-in EDL power supply: 03030997 (2.1 ft cable; extension cable 03030998); driver with long cable for an external power supply: 03030793; adapter N3150303 for use of either driver on AAnalyst 200/400
