Foxy R1 and Foxy R2 Fraction Collectors
Section 3 Programming
Figure 3-14 Threshold Settings menu
3-16
To program the fraction collector for Threshold peak detection:
1. Touch the Threshold Detection icon from the Method Set-
tings menu to open the threshold menu (Figure 3-14).
_10%
2. Enter the threshold as 1 to 99 percent using the Arrow
icons. The Up and Down Arrows increment or decrement
the numbers, the Left and Right Arrows move the cursor.
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. Threshold peak detection can be used alone or combined
with slope detection. You can control these options using
the icon in the upper right corner of the display.
· The None icon (left) indicates that Threshold
detection is Off.
· The Intersection Venn diagram icon (middle)
indicates that both Threshold and Slope 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 Threshold or Slope detection are true
fraction collector isolates the peak. This is also
considered a logical OR.
Touch the icon to toggle the selection.
