?a new problem with front inlet shutdown in high efficient GCMS

Question asked by walleed on May 23, 2020

 Dear colleagues  

   we encountered a new problem with front inlet shutdown in high efficient GCMS , the inlet itself appear OK before the beginning of run method and still OK during syringe wash and sample drawn but before injection the sample we find that the pressure decreases continuously and no injection is happen then the instrument gives front inlet shutdown.

i tried to restart the GC ,changing the method and unchecked the readiness of the front inlet but frailer to solve this problem.

does any one can declare this problem and how to solve it.

                                         many thanks
