I am looking for a Kromasil 100-C4 (150 x 4.6 mm, 3.5 µm); the batch number should NOT be 0000004828
This is the only batch that currently can be provided by the manufacturer and they will not manufacture a new batch soon.
For method validation, I'd like to apply at least a second batch (an older one).
Might be that there is such a column in stock anywhere (column supplier, in anybody's cupboard or anywhere else).
Thank you so much for your replies
Regards
Florian
