3.1.1 Components for sample preparation
As a TIC lock the multi N/C 2100S uses a septum lock. The septa which are normally
used are temperature resistant and have a high puncture tolerance. The septum lock is
available in the multi N/C 2100S pharma model, but it is not used.
As TC lock a septum-free lock is integrated into the multi N/C 2100S. The septum lock is
used for sample supply for TC and TN determinations. The septum lock ensures a high
particle handling capacity and low carry-over. A pneumatically driven folding mechanism
provides entry to the reactor (combustion, TC/TN).
The system tightness between the lock and the syringe is achieved by a septum on the
syringe during injection.
