Injection depth setting in SPME mode
Injection Depth is the distance from vial locator and the Fiber tip. For different depths set,
autosampler exposes only Fiber; Fiber and needle; Fiber, needle and Fiber holder.
Warning
Ensure that:
• The needle is aligned over the centre of the vial locator on the injector;
• The vial locator fits properly on the injector;
• The needle has to enter the injector without trouble and penetrate the septum
without any excessive bending: If it does not, check the injector septum, type of
syringe used and needle tip type;
• when the needle is in the port, ensure that it has a little further room to go down
(about 1-2 millimetres).
