Electrodeless Discharge Lamps
for greater brightness
EDLs are typically much brighter and, in some cases, provide better
sensitivity than comparable HCLs. EDLs are preferred for certain volatile
elements. They offer better precision and lower detection limits for
analyses that are “noisy” due to weak hollow cathode emission.
PerkinElmer System 2 EDLs consist of the element or a salt of the
element sealed in a quartz bulb containing an inert gas atmosphere.
When an RF field of sufficient power is applied, the inert gas is ionized
and the coupled energy vaporizes the element and excites the atoms
inside the bulb, resulting in the emission of the characteristic spectrum.
PerkinElmer’s System 2 EDLs consist of two major components: a dual-
channel power supply with matched dual RF driver assemblies, which
allows simultaneous, independent operation of two EDLs, and the
interchangeable lamp sleeves. The lamp sleeve contains the pre-aligned
bulb for the element of interest. The sleeve has the same exterior
dimensions as the PerkinElmer HCLs, allowing System 2 EDLs to be
used in the same lamp mounts and turrets.
■
System 2 EDLs are as easy to use as an HCL. Just install the lamp,
turn it on, and set the current. Changing lamps requires only seconds
because the pre-aligned bulbs require no additional adjustment.
To ensure operator safety, a built-in interlock prevents lamp operation
if the lamp is not properly installed.

EDLs provide greater light
output and longer life than
corresponding HCLs
For certain elements such as Arsenic and Selenium, EDLs will
also provide improved sensitivity and lower detection limits.
System 2 electrodeless discharge lamps provide the optimized
spectral output needed to get the maximum performance from
PerkinElmer atomic absorption spectrometers.
