Fig. 22 : µl pick-up injection: injecting sample.
For the next sequence the first withdrawal of transport solvent is omitted,
unless a wash routine is performed or the AS 3900 has emptied the
buffer tubing into the waste. In those cases the sequence is completely
repeated.
Air segment
If an air segment has been programmed, it appears at the front of the first
plug of transport liquid and at the front of every sample plug. An air
segment can be programmed in the system settings (See page 34).
In the µl pick-up mode, the air segment at the front of the sample
plug is injected into the HPLC system.

Unpacking
In case of µl pick-up injections, there will be no air pressure
(headspace pressure) on the vials, to avoid sample errors due to air
expansion during vial exchange from the sample vial to the
transport solvent vial.
Inspect the AS 3900 for indications of damage. Damage that occurs to
the AS 3900 in transit, indicated by damaged containers, is the
responsibility of the carrier and should be reported to the carrier
immediately. Shipping containers should be inspected by the carrier if a
claim is filed.
For contents of shipping containers see the packing list in container.
Before using the AS 3900 allow the instrument to acclimatise for a
period of 1 hour.
It is recommended to store the shipping container of the AS 3900. It has
to be used if it should be necessary to ship the AS 3900 for service
purposes.
Lift the AS 3900 as shown below in Fig. 24.
