YMC-Pack C4 Analytical HPLC Columns
YMC-Pack C4 is a low hydrophobicity material with a high coverage of monomeric bonded chemistry. Due to shorter alkyl chains it has a lower hydrophobicity than both C18 and C8 phases. Therefore retention times of non-polar samples tend to be shorter on YMC-Pack C4, making it an ideal choice for faster separations.
Features
- Low hydrophobicity material
- High coverage monomeric bonded chemistry
- Ideally suited for separations of biological materials
- USP listing L26
