Shodex Asahipak NH2P-50 Series HPLC Columns
Shodex Asahipak NH2P-50 series columns contain polymeric packing material modified with amino groups making it suitable for analysis that requires hydrophilic interaction chromatography (HILIC). It is a robust HILIC column with excellent chemical stability and a wide pH range of 2 – 13. It can be used for many general applications including saccharide analysis.
- Suitable for saccharide analysis using HILIC mode
- Polymer-based packing material provides excellent chemical stability and minimum deterioration over an extended time period
- Amino groups bonded to weak anion exchange resin
- pH stability of 2 to 13
- Easily regenerated by washing in an alkaline solution
- Suitable for evaporative light scattering detector (ELSD), corona charged aerosol detector (CAD), and mass spectrometry (LC-MS/MS)
- Asahipak NH2P-40 has a smaller particle size of 4 µm to provide higher theoretical plates than NH2P-50
- L82 USP classification
