2 GRACE Vydac Vydac columns, manufactured by Materials Technologies / Discovery Sciences, were developed for bioseparations and became the benchmark for the reversed-phase separation of proteins and peptides. Vydac 00Å wide pore phases are available in a wide range of dimensions from nano and capillary, to micro and analytical, to preparative and process scale.

A variety of reversed-phase materials makes this product line suitable for the LC-MS analysis of small peptides to large intact, undenatured proteins. Trifluoroacetic acid (TFA) is frequently used for improving peak shape and symmetry in reversed-phase separations of peptides and proteins. Although its volatility permits easy removal from preparative fractions, it does contribute to the background signal at low UV wavelengths and also has a suppression effect on electrospray MS ion generation. Although a TFA concentration of 0.% is commonly used, changing the TFA concentration can change reversed-phase selectivity of peptides. The Vydac MS phases have undergone proprietary modifications that reduce the dependence on TFA and other ion-pairing reagents. In selected cases, these columns also perform well without the addition of TFA, acetic or formic acid. Figure shows the separation of four peptides on a 8MS column. Peak shapes are maintained down to 0.0% TFA, although selectivity changes.. Neurotensin -8 (fragment). Oxytocin. Angiotensin ll.

Separation of peptides on Vydac 8MS 0 Everest Columns High resolution for complex peptide digests Unique selectivity for hydrophilic and hydrophobic peptides The Everest phase is a monomerically bonded 00Å phase. A novel, proprietary silica treatment and unique bonding chemistry result in unique selectivity and increased sensitivity for hydrophilic and hydrophobic peptides from complex digests. This improved bonding also leads to increased recovery and the ability to detect trace level peptides. Everest columns are available from nano/capillary to preparative and process scale. Figure (see page 0) shows the analysis of a peptone on Everest C8 (8EV). sales@hichrom.co.uk Tel:
3 Vydac TP s Referenced in a large number of patents and publications Polymeric bonded phases have long column lifetimes The Vydac TP range of phases was the first generation 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 00Å TP silica give polypeptide molecules complete access to the interior of the silica pores. Column Selection for Polypeptides The appropriate reversed-phase column for a polypeptide separation should be selected based primarily on the hydrophobicity of the polypeptide and secondly on its molecular weight. Subtle differences in selectivity can be observed between analyses using 8MS or 8TP polymeric and 8MS or 8TP monomeric bonded C8 phases. Figure shows a comparison between the selectivity of the polymeric 8TP and monomeric 8TP phases for a mixture of peptides. Applications for Vydac MS and TP columns are summarised below. 08MS and 08TP Ideal for biomolecules 5-0,000 Da Enzymatic digest fragments Natural and synthetic peptides MS and TP Polypeptides larger than -5,000 Da Hydrophobic polypeptides Glycoproteins Haemoglobin variants Histones Human growth hormone Insulin variants Membrane proteins Column: Everest C8 (8EV) (50 x.6mm) Eluent: A: % TFA in H O B: % TFA in CH CN T(mins) %B Flow rate: ml/min Temperature: 0 C Mins Figure.

Beyond the 6 EPA priority pollutant PAHs, these columns are used to separate many other PAHs, such as methylated naphthalenes. Vydac 0TP columns also have application in the analysis of carotenoids, retinoids and vitamins. The higher carbon-loaded 0TP phase offers alternative selectivity and is also ideal for derivatized PAH samples or high throughput PAH analyses.
