XBridge

Columns

1

Thank you for choosing a Waters XBridge

column. The XBridge

packing

materials were designed to provide excellent peak shape, high efficiency,
and excellent stability for acidic and basic mobile phases. The XBridge

packing materials are manufactured in a cGMP, ISO 9001:2000 certi-
fied plant using ultra pure reagents. Each batch of XBridge

material is

tested chromatographically with acidic, basic and neutral analytes and
the results are held to narrow specification ranges to assure excellent,
reproducible performance. Every column is individually tested and a
Performance Test Chromatogram is provided with each column along
with the Certificate of Acceptance.
