There is no peak when I used my TCD detector on HP5890 series II.
The reference flow rate is 18 ml/min and the column flow (no makeup gas) rate is 6 ml/min, there is no peak. Currently I just want to see a peak regardless the quality of the peak. Can I see a peak if the flow rate ratio is not correct? or maybe the peak quality is not good but I can still see a peak? What change should I made for the flow rate if I want to see a peak? Increase the reference flow rate or decrease it?
Thanks so much! I checked everything I can for my TCD detector but there still no peak. Please help!!!
