Wow, your peaks are super close to each other! Anything minor will affect your chromatogram. Maybe you should search for a better method? Anyways, what impacts the most are flow (are you running a gradient method?), organic concentration (again, gradient…
You can calculate the pressure on the flow cell by disconnecting the inlet capillary in the VWD. So the pressure in the VWD is the system pressure MINUS the pressure without VWD

That is certainly worse. There's one last thing to try that is not invasive. Create a blank method that is, oh, 2 or 3 hours long with the oven at your normal final oven temperature and the electron multiplier turned down to, oh, 700V. You want the hydrogen…
The injection port must have sufficient flow through it to eliminate any possibility of oxygen entering the system. The Split/Splitless injection port needs 20 ml/min or more going through it for that to happen. 20 ml/min of gas is a very small amount…
Hello, the time is taken from the computer clock. Changing the time during a run will make the times on the samples change. You cannot manually edit the time on a run. Your data going forward will reflect the correct time.
