Electronic Flow Control Type 25 - Scion Instruments 436-GC Service Manual

436-GC/456-GC

Electronic Flow Control Type 25

The EFC25 is almost identical as the EFC21 the only exception is that the
pressure is monitored at the module itself rather than at the Injector. This allows
the EFC25 to be used with Gas or Liquid Sample Valve's and Purge and Trap
devices upstream from the Injector.
