This operating procedure is always advisable before using a new syringe with low capacity
(like a 5 or 0.5
μ
L) or a new 10
μ
L syringe with Teflon tip plunger. The following procedure
will allow to obtain the proper lubrication of the plunger.
To prepare a new syringe proceed as follows:
1. Fill a 4 mL vial with fresh solvent (hexane is recommended) and place it in the D position
of the washing tray of the AI 3000/AS 3000 II.
2. From your PC, enter the Data System and then access the AI 3000/AS 3000 II method
page. Select the following parameters:
• Pre-injection Solvent: D
• Pre-injection Cycles: 15
3. Enter the File menu and click on Send Method to Sampler .
