Adjusting the Element Range

Thermo Scientific
Figure 11. Adjusting the Element Range
Multi-Range tests are used to either preferentially excite specific elements for increased
sensitivity, or to cover a wider element range than one Range alone can provide. Most modes,
when enabled, will use several Ranges in sequence to produce a combined analysis result. In
typical Metals analysis applications, Main Range is used for the analysis of most elements,
Low Range is utilized for the subsequent high sensitivity analysis of V, Ti, and Cr, High Range
is is used to optimize the sensitivity for the elements from Palladium (Pd) through Barium
(Ba), and Light Range is typically used in light element analysis. Multi-Range switching can
be set to activate off time alone, or, when time switching is disabled, off settings in the
General Metals grade library. In most modes, Low and Light Range add the capability to
analyze light elements which cannot be efficiently excited by Mid Range.
Select the mode you wish to configure from the Mode Menu. You can set different
configurations for different modes.
The Element Range Screen enables you to directly enable or disable any Range, or control the
time that a Range alters the irradiation of the sample before auto-switching to another Range.
Select the checkbox next to the Range you want to use to determine exactly which of the
Ranges contained in your Analyzer is used for sample testing. Selecting an empty checkbox
will enable that range and place a check into the box as an indicator. Selecting a checked box
will disable the Range and clear the box.
