Help me with the column

[shantaram]

I have to purchase a column having dimensions as follows:
(250*4.6mm) packed with aminopropylsilyl stationary phase of 5µ particle size.
Please provide the required information regarding the column suited best with the above criteria.
The same column i want to use as an alternate to (300*3.9mm) packed with aminopropylsilyl stationary phase of 5µ particle size.

You have described a widely available Amino-phase column in one of the most common lengths, internal diameters and particle sizes.

Pick up a supply catalog or go on a website and look. The first catalog I looked at gave 16 options.
