Difference between TP and MS

Vydac TP

Vydac TP was the first range of wide pore media phases developed in the Vydac range and became the industry standard for peptide and protein separations. The large pores of the 300A TP silica give polypeptide molecules complete access to the interior of the silica pores.

The general features of Vydac TP include:
Long column lifetime and negligible phase leaching
Reliable protein purifications, scalable from analytical to preparative scale
Referenced in a large number of patents and publications

Vydac MS

Vydac MS columns are a later development from Grace for the reversed-phase HPLC separation of biomolecules. A proprietary surface treatment and bonding process give Vydac MS columns unique selectivity. A variety of reversed-phases makes this product line suitable for the analysis of small peptides to large intact, undenatured proteins.

The general features of Vydac MS include:
300A pore size spherical silica
Five reversed-phase chemistries
Excellent peak shape with little or no TFA
High protein recoveries make scale-up easy

The improved selectivity for peptides on the Vydac MS columns results in better primary structure definition and easier identification of degradation products and other protein characteristics.
