With a view to improving the correspondence between liquid chromatography column brand names and the reagents used to describe the stationary phases used with these columns, an overall review of all the monographs concerned has been undertaken. The names of the reagents and their definitions have also been reviewed to ensure that these stationary phases are described as clearly and consistently as possible.
This review only affects the names of the reagents published in the monographs, the columns listed in the Knowledge Database and the analytical method have not been changed.
The modified monographs (and any reagents concerned) will be published gradually, with each new supplement. The changes will be flagged by lines in the margin.
A similar review of the reagents used to describe the stationary phases for gas chromatography columns will be undertaken in preparation for publication of the 10th Edition (to be published, July 2019).
