Air segment in the pickup injection
If an air segment was programmed, this will appear at the beginning of
the first segment of the transport solution and at the beginning of each
sample segment.
The following is to be observed for this injection technique:
Note
The air segment at the beginning of the sample segment is injected
onto the separation column.
Note
No overpressure is permitted to be applied in the sample vessel,
because the air segment would expand during the change from sample
position to transport position. This could lead to a considerable error
with respect to the injection volume of the sample.
