All oligos from Eurofins Genomics are analysed by MALDI-TOF MS or ESI-MS as part of our analytical quality control (QC) prior to shipment.
Oligos containing wobbles (mixed bases) cannot be accurately evaluated by these QC methods due to the presence of multiple sequences.
The QC reports containing the MS spectra are either provided by default or on request and are available in your online account under "My Orders".
