Hi Everyone,

We are experiencing a "weired" problem with EuroVector
EA.  During the analysis of CN, the flow rate suddenly
dropped from 70 mL/min to 20 or 30. The rate can only
be increased to 50 even the pressure has been
increased up to almost the limit of the EA.  When we
found this problem, we checked all the connections and
did leaking test, and they are fine. Also, the reactor
and reduction tubes are new ones, and quartz insert is
new too.  I was wondering if anyone has experienced
such problem before and thus can give us some
suggestions about the possible causes.   Thanks in
advance,
