Accurate Cyanocobalamin analysis by AOAC 2014.02 requires Eclipse C18 Plus column.
Application Area: Vitamin B12 analysis
"We tried to evaluate performance of the AOAC 2014.02 method in analysis of cyanocobalamin in infant formula and adult nutritionals. The method using the listed column provided a shoulder of unknown compound on cyanocobalamin peak. When we replaced the listed column by the Exclipse C18 Plus column we could find that shoulder on cyanocobalamin peak separate as a separate peak which later on was identified as adenosylcobalamin peak. Thus Eclipse C18 plus column improved the method performance remarkably and could not only estimate cyanocobalamin amount in the sample correctly but could also also analyze adenosylcobalamin."
