We have a Perkin Elmer Clarus 590 GC-FID instrument with manual pneumatics and it has been running well. Recently we loaded a new method and the flowrate changed from psi to ml/m. When this happened, we noticed the flow rate spiked to 1400 ml/m immediately and we noticed a rushing sound through the instrument. We stopped the flow immediately. Now, when we tried to run an analysis at a 1.2 ml/m, we did not see any peaks. Also, we tried to update the TotalChrom software, but it did not revert back to psi.
We would appreciate any advice or suggestions on how to overcome this problem.
