ASKS
Choose Auto Process on the Process menu to automatically perform the
following tasks simultaneously:
• Injection alignment
• Baseline alignment
• Artifact removal
You can also set each option individually.

LIGNING THE
I
NJECTION
Choose Injection Alignment on the Process menu or the toolbar to shift the x-
axis on a sensorgram to begin at zero. This option is useful when there is a
space before the beginning of the injection.
Sensorgram data display with injection alignment applied automatically. You
can adjust the alignment.

LIGNING THE
B
ASELINE
Choose Baseline Alignment on the Process menu to align the y-axis and set
the baseline for the sample.
The baseline of each sensorgram is aligned automatically within a specified
period of time before the injection point. You can adjust the baseline
alignment.
• Auto — aligns baseline automatically for all selected sensorgrams
• Selected — After you select a region, the software calculates
median values in the selected sensorgram region and reduces the
sensorgram value by the resulting value; only the selected
sensorgrams are adjusted

RTIFACTS
Surface Plasmon Resonance (SPR) signal artifacts occur for a number of
reasons, including pump refilling, injection valve switching, and accidentally
injected air bubbles.
Artifacts can be removed in two ways:
• Auto — all data is scanned for artifacts. Bad data is removed
automatically
