a. Grasp the syringe barrel near the mounting bracket.
b. Turn the syringe counterclockwise until it is released from the
mounting bracket.
Install a new syringe
If you need to install a syringe different in size from the original syringe, refer
to the following table for available syringe sizes. Be sure to enter the new
syringe size in the Configuration screen. (See page 208.)
To connect and initialize the syringe:
1. The syringe package contains the unassembled plunger and spare
syringe barrel. Remove each component from the package and wet the
Teflon tip of the plunger with mobile phase or methanol.
2. Gently insert the plunger into the syringe barrel, about 3/4s down the
length of the barrel.
3. Dip the end of the syringe into mobile phase or MeOH, and draw the
liquid until the syringe is partially filled.
4. Hold the syringe vertically and gently tap the barrel so that the liquid
settles on the plunger tip and any air rises to the top.
5. Gently push the plunger to expel the air, without bottoming the plunger
in the syringe barrel.
6. Screw the new syringe partially into the mounting bracket. Do not
tighten.
Caution: It is very important not to bottom the plunger in the syringe
barrel, because this will damage the Teflon plunger tip and negatively
affect syringe lifetime.
