I am running a Horiba CLA-510SS for NO/NOx analysis. It is being ran through the ES-C510SS Sampling Unit.
I am seeing a large amount of drift when I run a sample of known concentration on the unit. In the neighborhood of 50ppm swing +/-.
Does anyone have experience with this? Could this be due to back pressure in my vent system?
Any help would be much appreciated.
