LiChrospher® 100 RP-18 and LiChrospher® 100 RP-18 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. For LiChrospher® RP-18,
a masterbatch concept, where several individual batches are used to produce a large batch (“the masterbatch”)
of the LiChrospher® RP-18 sorbent, is used with the aim of eliminating the variation between the individual batches.
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.
