INTRODUCTION
Cogent TYPE-C™ HPLC columns are fully compatible with Supercritical Fluid Chromatography (SFC) in terms of both hardware durability and stationary phase stability.
Hardware & Material Compatibility
- Column hardware (stainless steel tubing, frits, and end fittings) is resistant to the pressures and chemical environment typical of SFC systems.
- The TYPE-C™ silica-based stationary phase is chemically bonded and thermally stable, making it suitable for exposure to supercritical CO₂ and common SFC co-solvents (e.g., methanol, ethanol, isopropanol).
- No degradation or swelling of the packing material is expected under standard SFC operating conditions.
Application Suitability
While the columns are physically and chemically compatible with SFC, we currently do not maintain SFC instrumentation in-house and therefore cannot provide validated SFC application data or method development support.
However, based on the unique surface chemistry of TYPE-C™ silica (featuring a covalently bonded silicon-hydride surface), these columns may offer distinct selectivity advantages in SFC, particularly for:
- Polar and moderately polar compounds
- Compounds that exhibit poor retention or peak shape in traditional silica or C18 SFC columns
- Applications requiring orthogonal selectivity to standard reversed-phase or bare silica SFC phases
Summary
| Feature | Cogent TYPE-C™ Columns in SFC |
|---|---|
| Hardware compatibility | ✅ Yes |
| Stationary phase stability | ✅ Yes |
| Application support | ⚠️ Limited (no in-house SFC) |
| Selectivity potential | ✅ Unique, especially for polar analytes |
We welcome inquiries and are happy to provide technical guidance on column selection and method considerations, but we currently do not offer validated SFC methods or performance guarantees in this mode.
