We tried to back flush the the transfer line from the GC to P&T by pushing methanol. This did not work and methanol came out. We turned on the flow to GC and the rest of the methanol came out. We are not able to keep the flow to gc any more! We do get enough flow to the head of the column, but the gas is constantly coming out of split valve; so the system shut itself off after about a minute. We have turned off and on the system a few time without any success. Any suggestions is greatly appreciated.
