Thermal Conductivity Detector response
« on: March 03, 2008, 04:53:21 AM »

I have always believed something that I was told about TCD response factor being close to '1' for most compounds (except water)... therefore, using Area% methods are fine for plant production needs.  Recently I found that my Weight% numbers vary up to 7% from my Area% values and water is not even a factor because I dried the sample with sodium sulfate anhydrous.  Have I been wrong/misled about TCD responses and Area% methods?  Are straight Area% methods really that far off of Weight% methods?

Thanx in advance to any kind soul who spends time to respond.
