Some data for plate count and asymmetry factor (Fas) was incorrectly recorded on the certificate of analysis or COA for some columns between 2017 and 2021. This was due to incorrect settings in the software calculation of the one specific instrument used to certify columns.
We apologize for any inconvenience.
