The Merlin MicroSeal Septum is a unique long-life replacement for the conventional silicon septa on split/splitless and PTV injectors. MicroSeal is a trademark of the Merlin Instrument Company, Half Moon Bay, CA, USA. Functionally, the MicroSeal provides a micro valve two-step sealing mechanism (see Figure 2.50) ...
