4.5 Pickup injection
The switchover sequence for the pickup injection is as follows:
Initial situation
1
The injection valve is in INJECT position. The sample needle is in
washing position.
2 Rinsing the washing reservoir
The washing reservoir is filled several times (the number of times can
be programmed) with the syringe volume. This takes place after a
washing sequence or after the buffer tubing has been emptied. The
injection valve remains in INJECT position. Note that the transport
solution must be compatible with the eluent.
3 Filling the aspirating line with transport solution
For the first injection, the syringe aspirates a segment of transport
solution in order to fill the sample line with transport solution.
