Monosized Polymeric Non-Porous
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.
Core-Shell Technology
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.
Thermally Modified Fully Porous
Through a proprietary thermal processing series of steps, we eliminate micropores and further improve consistency, column efficiency, inertness, ruggedness, and reproducibility.

Peptide Mapping
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.

With protein aggregate often at very low levels (<0.1% by peak area compared to monomer) and fragment separation a requirement, adequate resolution and peak shape have become even more crucial method outcomes. To address this need, the robust set of Biozen SEC columns were developed with a combination of UHPLC efficiency and higher sensitivity, to drive resolution and identification of even lower level targets.

Biozen WCX was crafted to consistently decipher between native protein variants that arise from PTMs within a therapeutics creation and development. The linear polycarboxylate chains grafted to monosized non porous polymeric particles, envelop and separate proteins from acidic and basic protein variants. With such a highly tuned and controlled manufacturing process, Biozen WCX HPLC columns affords scientists a way to reproducibly characterize heterogeneity while taking advantage of excellent recovery through high particle inertness and bioinert titanium BioTi™ column hardware.

Intact and Subunit Analysis
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.

Intact Mass Analysis
Intact mass can give indications not only of relative abundance of glycoforms , but also stability as degraded mAbs will not give good charge envelope by ESI-MS. Intact Mass with a high resolution MS to identify PTMs, especially relative abundance of glycoforms , combines extremely well with the fast run times and tight peak shapes provided by the Biozen Intact XB-C8 and Biozen WidePore C4.

Drug Antibody Ratio (DAR)
With a direct effect on efficacy and safety, conjugation for each ADC must be well understood. The Biozen Intact XB-C8 provides an excellent vehicle for determining drug load distribution and DAR for ADCs. Its large pore size allows intact ADCs to interact with a moderately retentive stationary phase while the core-shell particle supplies increased efficiency to deliver the required resolution between ADC species with differing drug loads.

Peptide Quantitation
When quantitating signature peptides from biological matrices, you need sharp peak shape and sufficient retention of hydrophilic peptides to prevent any signal loss from matrix suppression regions. Both Biozen Peptide columns were developed to deliver excellent selectivity for even closely related peptides. Additionally, they build on this body of valuable characteristics with unique ways of delivering sharper peak shape for basic peptides; Biozen Peptide XB-C18 blocks secondary surface interactions via isobutyl side chains, while the Biozen Peptide PS-C18 contains a positively charged weak base that repels other basic species.

Glycan Analysis
The unique selectivity of the Biozen Glycan was designed to provide higher order separations of released and labeled glycans. With a 2.6 μm core-shell particle size, customers using either HPLC or UHPLC systems can draw upon a high efficiency Biozen Glycan particle run at higher linear velocities to easily provide sharper peak shapes and faster elution windows, without high UHPLC pressures. Under HILIC-FLR or HILIC-MS conditions, the Biozen Glycan excels with increased polar retention and selectivity.
