STRANGE COLUMN

[chris knutsen]

We have a method for a client that calls for a 4.6 micron X 120 mm which contains 7 micron silica coated with C18. We are having a heck of a time finding this packing and wonder if anyone has any information that I can get to help us get this. We have expanded all of our resources.

Thanks

Alltech will pack custom columns upon request (www.alltechweb.com), and probably some other vendors will do so as well. We once had them pack a custom column that we couldn't find listed.

It is not a good description of the packing, also the column length is rather unusual. Custom-packed columns with 7 micron particles can be obtained from Waters, but the 12 cm might be tough.
