Ethylene Bridged Hybrid
[BEH] eXtended Performance [XP] 2.5 µm Column. The manufacture 
of XBridge XP 2.5 µm Columns begins with ultrapure reagents and 
are manufactured in a cGMP, ISO 9001 certified facility to 
control the chemical composition and purity of the final product. 
Well-controlled manufacturing processes result in industry-leading 
batch-to-batch reproducibility. Every column is individually tested. 
A Performance Chromatogram and Certificate of Batch Analysis are 
provided on the eCord
™
Intelligent Chip.
XP 2.5 µm Columns are based on the same base particle technology 
and bonded-phase chemistry as 1.7 µm ACQUITY UPLC
®
Columns as
well as XBridge 3.5, 5 and 10 µm HPLC Columns, thus enabling 
seamless transferability between HPLC, UHPLC and UPLC
®
platforms.
XBridge XP 2.5 µmColumns will exhibit maximum chromatographic 
performance when used on a member of the ACQUITY UPLC 
System family.
