Sequencing and oligonucleotides

Hello ABRF's users

We recently had a complaint about HPLC purified oligonucleotides used for
sequencing. The hybridization versus the target seems OK but there is a
strong noise background on the electrophoregram making the reading
difficult. Do you think that triethylammonium or ammonium acetate salts
used for HPLC purification
could be responsible for this effect ? I don't know if this can be a
plausible explanation for unsuccessful sequencing ?
By the way do you know the main causes for bad results in sequencing ?

Thank You
