The Biozen dSEC columns are packed with low pore volume silica coupled with a proprietary hydrophilic diol-type bonded surface chemistry that prevents the silica surface from interacting with protein samples.
With a new titanium BioTi™ biocompatible hardware to minimize priming, four particle platforms for optimal versatility and nine particle chemistries to maximize selectivity and sensitivity, Biozen UHPLC/HPLC columns for protein analysis are seamlessly designed to bring peace of mind to your analysis of biologics through:
Keep your mind at ease knowing that we’ve minimized the need for priming with a new titanium infused biocompatible hardware and frit that doesn’t interfere with protein or peptide integrity!
A: UHPLC Pressure Rating Allows for more experimental design space; room to increase flow rates for increased throughput |
B: Better Controlled ID Versus PEEK Hardware Improved column-to-column performance, providing more consistency and easier method validation |
C: Biocompatible Titanium Liner |
D: Improved Recovery and Peak Shape Better column-to-column consistency, ease of use, and troubleshooting |
E: Strong Stainless Steel Walls Help Prevent Movement Under Pressure |
F: Biocompatible Titanium Frit |
All four of the Biozen particle platforms were individually designed and built by Phenomenex to take advantage of integral levels of performance, ruggedness, and reproducibility for protein characterization applications. Individually, each platform differs in the proprietary processing techniques used to control particle size and morphology.
The Biozen dSEC columns are packed with low pore volume silica coupled with a proprietary hydrophilic diol-type bonded surface chemistry that prevents the silica surface from interacting with protein samples.
Meticulously controlled monosized particle technology secures incredible particle consistency that leads to improved and reliable efficiency. This innovative non-porous particle serves as the perfect backbone for complex ion-exchange chemistries.
Using sol-gel processing techniques that incorporate nano structuring technology, a durable, homogeneous porous shell is grown on a solid silica core. This highly optimized process combined with industry leading column packing technology produces highly reproducible columns that generate extremely high efficiencies and sensitivity.
Through a proprietary thermal processing series of steps, we eliminate micropores and further improve consistency, column efficiency, inertness, ruggedness, and reproducibility.
The Biozen Oligo LC column brings a unique combination of improved chromatographic efficiency from its core-shell morphology and high pH stability necessary for oligonucleotide characterization. Biozen Oligo is packed in a unique bio-inert titanium hardware developed to mitigate non-specific interactions that lead to analyte loss, distortions in peak shape and carry over. Confidently maximize resolution and reproducibility throughout the most demanding of method extremes with Biozen Oligo.
Bio-inert hardware gives clear separation of the sense and anti-sense strand. View application>>

Digested mAbs or ADCs typically include a large body of compounds which are crucial to understanding post translation modifications. So we designed two Biozen Peptide columns to offer uniquely different selectivity profiles for these types of bioseparations. Each allows for fast and effective elution windows by utilizing either high efficiency core-shell or thermally modified fully porous particles to gain sharper peaks, better peak capacities, and overall higher sensitivity.

Impurity profiling and characterization of intact biologics and fragments is a challenging undertaking because of the need to identify very small differences between variants. Both Biozen Intact columns. contain skillfully manufactured large pore core-shell particles that provide narrower, taller peaks in conjunction with higher resolution between the target mAb HC/LC, Fc/Fab, or isoforms.
