This booklet provides general information for all Infi nityLab 
Poroshell 120, ZORBAX, Pursuit, and Polaris normal-phase 
and HILIC columns. Initial sections include information for both 
normal-phase and HILIC columns. Because some method 
parameters and column care instructions are different for HILIC 
versus normal phase, those sections are broken out separately 
in the last few pages. For additional information about your 
specifi c column or family, 
see www.agilent.com/chem/columnchoices
Getting Started
A QC Column Performance Report, including a test chromatogram, 
comes with every Agilent column. The QC test instrument is modifi ed 
(optimized) from a standard instrument to minimize extra column 
volume, so it may vary from the system used in your lab. This allows a 
better evaluation of the column and assures a more consistent product. 
An LC system, optimized for low volume columns, will generate similar 
results to the chromatogram on your QC Performance Report.
