Longer-chain columns *are* available. For example:

http://www.phenomenex.com/Products/HPLC ... eous%20C30

It's just that they have limited utility.

Good Morning Praveen,

In Addition to Tom's Information have also a look on YMC's Website for C30, a Special column for carotinoide application. For sure it is possible to make silanes to get >C18, as Tom mentioned they have limited Utility for Special applications. But for Special applications it is nice to have such phases.
Have an excellent day.
Gerhard
