RNA Extraction... ( Still )

I was wondering if the pH of the phenol can affect the efficienty of the
phenol/chloroform extraction...

I'm still stuck with low 260/280 ratio and was wondering if a lower pH
value for the phenol could interfere with the RNA and/or the quality of
the extraction, leading to impurities...

I measured betwwen 6.0 and 6.5 for the phenol when it should have been
7.6   I think...

Then again, can I trust a pH measure where pH paper is wet with a drop of
phenol who's so strong...

Thanks for anything that could be related  near or far ...
