many thanks for all persons spent their time to reply me about solving the problem
the problem solved by changing quad and quad driver by Agilent regional represent
but i have a notice that through explain my problem no one from Agilent engineer give me a remarkable advice to track the problem .
my advice to all people to track this problem to inspect the quad and if any black colour appear inside the quad this means the quad need replacement

The quad is not a replaceable part on a single quad GCMS, the analyzer should be replaced as an assembly. There is a long explanation about black marks inside the quad, but suffice to say that it is all sample residue of ions and unionized molecules. It can be exacerbated by air leaks, column bleed, bad gas, and the way the operator is running the system.
many thanks for your replay , i tooled what happen exactly, and i agree with all your above points
