Correction to: Anal Bioanal Chem

The authors would like to call the reader’s attention to the fact that unfortunately the formula for the O17 correction parameter “a” is reported incorrectly as
$$ \frac{R17(sam)}{R18(sam)}={\left(\frac{R17\left( RM-O\right)}{R18\left( RM-O\right)}\right)}^a $$
The formula can be found in the section titled “Data normalization: Realization of VPDB scale for traceability” and should read:
$$ \frac{R17(sam)}{R17\left( RM-O\right)}={\left(\frac{R18(sam)}{R18\left( RM-O\right)}\right)}^a $$
