YMC-Pack Diol SEC columns are available in four tightly controlled porosities and are suitable for separation and molecular weight determination of a wide range of peptides, proteins, oligonucleotides, carbohydrates and other biopolymers with molecular weights of approx 200 to several hundred thousand kDa.
YMC-Pack Diol stationary phases are surface modified for a versatile alternative to underivatised silica. Advantages include a shorter equilibration time as well as good selectivity. Due to this short equilibration time, the Diol phase is a perfect choice for SEC in comparison with underivatised silica.
Features
- Suitable for proteins, antibodies, their fragments and peptides
- Also applicable to carbohydrates and nucleic acid components
- Excellent reproducibility with minimal secondary interactions
- 2 µm particle size for UHPLC methods
