Answer:It is an arsenic-specific electrodeless discharge lamp for atomic absorption spectroscopy.
Answer:A compatible EDL driver assembly is required for each EDL lamp position on PinAAcle systems.
Answer:The two source technologies can support arsenic AA methods, but their electrical requirements and operating settings differ; instrument compatibility must be confirmed.
PerkinElmer System 2 arsenic electrodeless discharge lamps supply element-specific radiation for atomic absorption measurements of arsenic. Unlike a hollow cathode lamp, an electrodeless discharge lamp uses an externally excited light source and can provide stronger spectral emission for elements whose conventional lamp signal is weak. The arsenic EDL is appropriate for compatible PerkinElmer AAnalyst and PinAAcle AA systems when the analytical method specifies this source type. On PinAAcle instruments, each occupied EDL position requires a compatible EDL driver assembly, which is supplied separately. Select the arsenic analytical wavelength, slit, and source operating settings from the validated instrument method rather than applying settings from a different element or lamp type. Allow the source and spectrometer to stabilize before calibration, and monitor background correction, blank response, standard recovery, and signal precision. Handle the lamp carefully, avoid contact with optical windows, and follow instrument procedures during installation and replacement.
