Overview
f(x) prepacked and precharacterized chromatography columns give you faster and more reliable mechanistic modeling during downstream process development.
- Precharacterized column — supplied with a Results of Analysis that provides you with column-specific data for use in mechanistic modeling workflow. Ensures accurate model parameter values and reduces the time you need for column characterization.
- High-quality prepacked columns — packed with high-productivity BioProcess™ resin by Cytiva experts.
- Lab-scale process development column format — resin packed in Tricorn™ 10/200 or 10/100 columns, which are tailored for experiments during process development and for process characterization.
f(x) columns for faster and more reliable mechanistic modeling results
To determine column parameters required for the model, you need to perform column characterization experiments. This takes time and requires expert knowledge to ensure that accurate parameter values are produced. With f(x) columns, your parameter values are instantly available, accurate, and include:
| Parameters included in the Results of Analysis for the following f(x) columns | ||
|---|---|---|
| Ion exchange and multimodal chromatography | Hydrophobic interaction chromatography | |
| Bed height (cm) | Yes | Yes |
| Total porosity | Yes | Yes |
| Interstitial porosity | Yes | Yes |
| Ionic capacity (μmol/mL), column specific and in resin backbone | Yes | N/A |
| Bed volume (mL) | Yes | Yes |
| Bead radius (µm) | Yes | Yes |
| Total specific adsorber surface area (m-1) | Yes | Yes |
| Specific adsorber surface area (m-1) | Yes | Yes |
| Ligand density (µmol/m²) | Yes | N/A |
| Ligand pKa | Yes | N/A |
| Axial dispersion (mm2/s) | Yes | Yes |
f(x) columns give you confidence about the column parameters used for your model (including colloidal particle adsorption (CPA) model), and free up your time to focus on generating molecule-specific data. They are a good complement to GoSilico™ Chromatography Modeling Software.
A suitable column format for your process development work
Tricorn™ columns are high-quality, prepacked columns for robust and reproducible process development and validation. Because of the narrow 10 mm inner diameter combined with 20 cm or 10 cm bed height typically used in biomanufacturing, these columns are especially suited to scale-down studies.
About mechanistic modeling in chromatography
Mechanistic models use computer simulations to decrease the number of experiments needed during process development, and increase the design space investigated. These simulations are based on known physiochemical phenomena involved in chromatography and offer you the following advantages:
- Cost reduction and time saving — more data obtained from fewer experiments, which accelerates your process development.
- Improved robustness and efficiency to fulfill regulatory demands on quality by design.
