Dionex As - Overlapping Sample Preparation

2.7.2 Overlapping Sample Preparation
When the wait operation is at the end of the sample prep phase (the
default), the
AS overlaps sample preparation. This means that while data
collection is occurring for one injection, the AS performs the sample prep
steps for the next injection (see Figure 2-15
). For a detailed description of
the schedule run flow of operations, see Section 2.7.6
.

End of Sample Prep Phase (Default)
Sample Overlap with Chromeleon or Chromeleon Xpress
If Chromeleon or Chromeleon Xpress is controlling the AS, front panel
settings for the wait operation are ignored. Instead, the Sample Overlap
option determines whether sample preparation is overlapped. Sample
overlap, which is selected in the Chromeleon Server Configuration
program, is enabled by default. For instructions on how to configure the
AS in Chromeleon, see Section B.3.12
