Fitting the Spectrum

88 Niton XL2 Analyzer User's Guide
• Ka, Kb, La, Lb, and/or Lg peaks of the three elements closest to where your cursor is
positioned on the energy scale (Bottom Right). This information is written with the
element symbol first, followed by either Ka (K shell alpha peak), Kb (K shell beta
peak), La (L shell alpha peak), La (L shell beta peak), or Lg (L shell gamma peak). An
example would be "Al Ka 1.48." To determine if a given element is present, look at
the count rate at that cursor position.
Note SpectraView cannot be used to determine exact element percentages in a sample.
By using the touch screen, you can select parts of the displayed spectrum and zoom in. Touch
and hold the stylus to the screen immediately before the area of the spectrum you wish to
enhance, then - still holding the stylus to the screen - sweep it across the area of the spectrum
you wish to see closer, lifting the stylus from the screen when you pass the end of the area of
interest. The screen will display vertical lines to either side of the area of interest, delineating
the boundaries of the area.
