Hi, could someone please explain what is meant by 'column bleed' in GC.

Would it be correct to say that there are normal (normal background signal by the stationary phase) and abnormal (a rise in baseline)?

thank you.

See my reply on your same post under the Gas Chromatography section :-)

Basically, you are correct

Try looking at these articles ... lumn-bleed ... s-low.html

Hope that helps
