CAUTIONARY NOTE

I. INTRODUCTION

Thank you for choosing a Waters™ XSelect 

XP

 and/or XSelect 

Premier HSS Column. The XSelect HSS packing materials 
are manufactured in a cGMP, ISO 9001:2000 certified plant 
using ultra pure reagents. Each batch of XSelect HSS 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 Chromatogram 
and Certificate of Batch Analysis are provided on the 
eCord™ intelligent chip.

The XSelect Premier HSS Column is offered with or without a 
VanGuard™ Fully-Integrated Technology [FIT] Cartridge. 
To address the desire to extend the operating lifetimes of 
analytical columns, the VanGuard FIT Cartridge is designed 
to prevent the non-desired introduction of sample matrix or 
particulates onto the column without degrading the separation. 
It can be easily replaced to restore separation performance and 
extend the analytical column’s lifetime. 

In addition, the XSelect Premier HSS Columns utilize 
MaxPeak™ High Performance Surfaces, an innovative 
technology designed to increase analyte recovery, sensitivity, 
and reproducibility by minimizing analyte/surface interactions 
that can lead to sample losses.
