What is the Difference Between C18 and C18 (2) HPLC Column?

[HPLC chemist]

Marketing and Sales BS!

[Multidimensional]

Not True. While most column marketing is BS (like just about every other product), the # designation after ODS usually refers to the silica type. ODS (1) was the original silica type; ODS(2) was a metal free cleaner version (less tailng and need for additives and ODS (3) is the latest version.

[Andy Alpert]

Actually, ODS1 is partially endcapped while ODS2 is fully endcapped [NOTE: "ODS" is short for octadecylsilane, = "C-18"]
