An adjustment of the autosampler is necessary:
¡
Before the first start
¡
After every syringe replacement
¡
After every manipulation of the locks (e.g., catalyst change and maintenance work)
¡
During recommissioning after transport or storage
During adjustment, you must adjust the canula to the following positions:
¡
Position 1 on the sample tray
¡
TC lock, septum-free: Entrance of the combustion furnace
¡
TIC lock with septum: Entrance of the TIC reactor (not for multi N/C 2100S pharma)
Always check and adjust all positions.
X- and Y-axis coordinates
Adjust the positions as precisely as possible in the x- and y-axis directions. The canula
must dip into the middle of the sample vessel at position 1.
The following values serve as orientation points:
