Instrument is configured with a pyrolysis injector. Recently the source was cleaned and after words we did not get any signal(peaks)for the analysis of samples. After replacement of the pyrolysis tube, inlet liner, and column we were able to see peaks. However, the TIC signal level is limited to about 4,500,000 to 5,000,000 counts. The TIC chromatogram looks as if the large peaks are attenuated down whereas the peaks at or below the above counts are not (no peaks are flat topped, nor does it appear the multiplier is saturated). The resolution of all peaks is excellent.
