Restek Reversed Phase Column Listing
Phase Type
Phase Type
Usage
IBD
Polar Embedded
•
RP and HILIC Modes
•
Great for DMPK (retention of polar acids) and QA/QC (excellent peak
shape of bases)
•
Lessens needs for mobile phase modifiers
PFP
Fluorinated
Not to be recommended over PFP Propyl unless PFP Propyl shows too
much retention
PFP Propyl
Fluorinated
•
RP and HILIC Modes
•
Great for DMPK (retention of protonated bases and halogenated
compounds)
•
Typically more versatile than Cyano columns in pH range
•
Lessens need for mobile phase modifiers
Amino
Amino
Traditional chemistry, highly used for the analysis of saccharides and
sugars
Cyano
Cyano
Traditional column chemistry for the increased retention and
selectivity of protonated bases
