A brief tutorial on How To Repair a Honda Engine Pressure Washer that won't start. Will not start after storage (plugged carburetor main jet). Moved In Over a Year and Won’t Start. 6890-Front inlet/pressure problems/won't start sequence. You did not mentioned the column you are using. If you use equal to or wider then 0.53mm then you must increase the pressure at the inlet to the GC, or may be you have a problem with the EPC then contact the technical support. 0 registered, 0 hidden and 10 guests (based on users.

Hey guys,
Hopefully someone might be able to help with this. I've been using a GC-MS for my analysis and recently changed the helium cylinder. Made sure to isolate the GC system from the gas line so it kept residual pressure while I went to get the other He cylinder, so the like stayed around 150 psi. I hooked up the new cylinder, loaded the method, but the inlet pressure and column pressure won't get close to the set pressure (gets to around 6-7 psi, slowly, when it's set to ~15), though it has no issues previously. Also, when I change the pressure on the GC the actual pressure will change to be about half the of the set pressure (i.e. set to 20, goes to ~10).
My first thought was a leak, but couldn't find one in the new connections I'd made from the cylinder to the gas line. I haven't touched the rest of it (gas line, GC internal plumbing) so I've no idea why this would happen all of a sudden. It gets to pressure when I turn the gas saver off, but this is (ideally) a temporary solution because I don't want to burn through the carrier gas.
For info, all the methods are the same as before, literally the only thing that's changed is the new He cylinder. Any help that you guys could provide would be MUCH appreciated. Thanks.
