CMS5000 Operating Manual
Search Window. . . . . . . . . . . . . . . . This value defines the acceptable retention
time range for a peak. The default value is 20
seconds. When using the default value, the
window is 10 seconds on either side of the
expected retention time in order for the
CMS5000 to make an identification.
Window Expand Factor . . . . . . . . . This option multiplies the retention time of the
peak by the Window Expand Factor to give
a period of time by which the search window
will be expanded. For example, if the peak
retention time is 10 minutes and the Window
Expand Factor is set to its default setting of
0.05, the 10 minute retention time will be
multiplied by the 0.05 Window Expand
Factor to equal 30 seconds. Then, 30
seconds is added to the Search Window. If
the default value of the Search Window is
20 seconds, adding the 30 seconds from the
Window Expand Factor to the Search
Window would increase the search range to
50 seconds.
Min Width . . . . . . . . . . . . . . . . . . . . The default value is 7. This value is the
minimum number of scans per peak, which
designates the area measurement for the
peak integration. Any peaks with less scans
than this value will be disregarded by the
software. Decreasing this number will
instruct the software to accept peaks that are
less broad than the default parameters have
accepted.
Max Width . . . . . . . . . . . . . . . . . . . . The default value is 70. This value is the
maximum number of scans per peak, which
designates the area measurement for the
peak integration. Any peaks that have more
scans than this value will be disregarded by
the software. Increasing this number will
instruct the software to accept peaks that are
more broad than the default parameters have
accepted.
