Waters Ultrasphere ODS? [Solved: Hichrom]

[dap]

Hello to all!
Recently we've got a drug master file with hplc method using "Waters Ultrasphere ODS, 250x4,6 mm, 5µm" column. However I can find only Waters Spherisorb ODS columns: http://www.waters.com/waters/keywordSea ... ory%7CCOLS
Could anybody help me please to define this column to buy it?

Original manufacturer was Beckman, maybe distributed by Waters. Now Hichrom is producing this packing material and offers packed columns.
Just google "Ultrasphere" and you will get to the needed information.
Good luck.
