An ODS column is stuffed with a packing of octadecylsilyl groups (ODS groups or C18 groups) chemically bonded to your silica gel provider. ODS columns are used for reverse-period chromatography.
—which provides a lot more time for you to influence a separation. A 2nd approach is to increase selectivity by modifying situations to make sure that just one solute experiences a substantial adjust in its retention time.
After regeneration in the column, conduct the system suitability examination According to the conventional check procedure from the anxious products.
