LiChrospher® 100 RP-8 and LiChrospher® 100 RP-8 endcapped are reliable and versatile traditionally produced 
spherical silica carriers with reversed-phase properties. They are well suited for the chromatography of acidic, neutral 
and weakly basic compounds, substances found frequently in all analytical fields. Their good column selectivity and 
performance ensure that these parameters remain constant from batch to batch and from year to year.

The traditional heart of HPLC is the “ready-to-use” column with threads at both ends onto which reducers for capillary 
connection are screwed. As a rule, precolumns are coupled with the main column via capillaries. If the column is 
exhausted, the user has two possibilities: Refilling, provided aggressive eluents do not prevent this by causing corrosion 
or worn threads, or the whole column is discarded. Column refilling without tube revision is problematic in view
of GLP since each column has a different “history” and a different pretreatment for each new assignment.
