chromatography

The separation of monomers from product-related impurities is quite challenging in process separations. It requires a thorough screening and an efficient resin to get efficiency in the purification process. Review the performance data of Bio-Rad’s mixed mode CHT™ Ceramic Hydroxapatite in achieving process separation efficiency and how it compares with various Capto media.

The best chromatography media should yield high protein purity and product recovery as well as be versatile enough to purify difficult samples. Bio-Rad’s CHT™ Ceramic Hydroxyapatite achieves this by virtue of being able to interact with the proteins through multiple modes, making the process extremely efficient. The whiteboard animation describes the mode of action of CHT.

What can chromatography peaks tell us? From the quality of column packing to the purity of separated proteins, a lot can be gleaned from the peaks. Here are some definitions that can help decipher what chromatography peaks can tell us.
