Chapter 5 Optimizing Instrument Settings

Adjusting laser
intensity
To efficiently optimize the laser setting, increase or decrease
the laser settings to the mid-setting of a continuously
decreasing laser window. To adjust the laser settings,
click-drag the slider bar on the Manual Laser Intensity/Sample
Positioning control page. For more information, see “Manually
adjusting laser intensity” on page 4-28.
Adjusting laser intensity depends on the following:
General strategy
As a general strategy for adjusting laser intensity:
Start at the default setting for your system
(approximately 1,800), or the setting in the loaded
.BIC file.
If the spectrum you obtain is not acceptable,
increase or decrease the laser in 50 to 100-step
increments or decrements and reacquire. For
more information on acceptable laser signal, see
“Signal saturation” on page 5-59.
If... Then...
You are using a .BIC file for the
same mass range and matrix.
Laser intensity may require only minor
adjustments.
You are using a .BIC file for the
same mass range, but different
matrix.
Increase or decrease the laser in 50 to
100-step increments (or decrements) following
the strategy described below. For more
information, see “Selecting a .BIC file” on
page 5-8, and “Laser intensity and matrix” on
page 5-57.
You are using default Instrument
Control Panel settings. The
mid-range default laser setting if a
.BIC file is not loaded is
approximately1,800.
This setting is typically too high for many
samples and matrix. Decrease the laser in 50
to 100-step decrements, following the strategy
described below. For more information, see
“Laser intensity and matrix” on page 5-57.
