SUPELCOSIL™ LC-18 HPLC Column
3 μm particle size, L × I.D. 15 cm × 3.0 mm
SUPELCOSIL™ HPLC Columns
Traditional HPLC columns, similar to Hypersil™
Our SUPELCOSIL silica-based HPLC column line includes over 40 bonded phase chemistries, in a range of particle sizes and column configurations from microbore to preparative scale. It is the original high quality Supelco product line referenced in many USP methods.
In the case of a few SUPLECOSIL phases, we have recommended alternatives based on more advanced column technology.
LC-18
A general purpose hydrophobic alkyl phase that is very retentive and gives good peak shape for a wide variety of compounds.
