How to improve the sensitivity for TCD detector? Increase or decrease the reference flow or make-up gas flow?? or any other way?
Thanks!
Thanks!
Maybe you should give us some idea of what you are trying to achieve, as I believe that this is not the first time that you have asked this question on this forum. If you are trying to get down to ppm levels, the best that you can achieve is about 5ppm. If you wish to go down to lower levels for fixed gas analysis, then you should consider using a PDHID detector. Your user manuals will give you information on the best flows.
