Installation and Commissioning of a Hilger Monospek D500 Scanning Monochromator

摘要

An account is given of the installation, commissioning, and testing of a Hilger 'Monospek' D500 scanning monochromator as an extra measuring channel on a Hilger E1000 direct-reading spectrometer equipped with a 5 kW inductively coupled plasma (ICP) source. The instrument was used successfully for the measurement of interference-free lines instead of those on the direct reader that suffered interference, and for the determination of the rare-earth elements in mineral samples. The monochromator is considered to be a very useful addition to the instrumentation in the Emission Spectroscopy Section, conferring a flexibility in the choice of lines that was not formerly possible.
