DESCRIPTION
Strongly basic anion exchanger, exchange capacity 50 µeq/g. Based on the original NUCLEOSIL silica gel. It is one of the first spherical silicas for HPLC and was originally developed by MACHEREY-NAGEL in 1974. It is exclusively manufactured in Germany and is still one of the most used HPLC silicas in quality control around the globe. Note: not suitable for fluoride.
