LiChrospher® 100 RP-18 and RP-18 endcapped HPLC columns are very reliable and highly versatile. These traditionally manufactured spherical silica based supports are designed for reversed-phase chromatography of acidic, neutral and weakly basic compounds – substances frequently found in all analytical fields. With LiChrospher® RP-18, several individual batches are used to produce a large master batch of the sorbent. This eliminates variations between different small batches, and ensures the sorbent’s excellent batch-to-batch consistency. Consequently, LiChrospher® RP-18 delivers highly reproducible results, and secures the reliability of your HPLC method.
