2. Enter the average peak width using the Up and Down
Arrow icons. The Up and Down Arrows scroll through the
available Peak Width settings.
Enter the average time duration of the expected peak, as
measured at the baseline. The fraction collector will use
this average time to detect peaks with widths ranging from
.2 to 2 times the programmed width. For best results,
choose the next larger peak width if your expected peak
width falls between the available options. For example, If
you expect a peak of 45 seconds, enter an average peak
width of one minute. The fraction collector will detect
peaks with widths ranging from 9 seconds to 2 minutes.
3. The icon next to the percentage shows what the fraction
collector will do with non-peak fluids. The icon that is clear
below the threshold indicates that non-peak fluids will be
diverted to waste. The icon that is shaded below the
threshold indicates that non-peak fluids will be collected in
tubes. Touch the icon to toggle the selection.
4. Peak width detection can be used alone or combined with
threshold detection. You can control these options using
the icon in the upper right corner of the display.
· The None icon (left) indicates that peak width
detection is Off.
· The Intersection Venn diagram icon (middle)
indicates that both peak width detection and
threshold detection must be true before the fraction
collector isolates the peak. This is also considered a
logical AND.
· The Union Venn diagram icon (right) indicates that
when either peak width detection or threshold
detection are true, fraction collector isolates the
peak. This is also considered a logical OR. If you are
