Hello,

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
