Blossmate Chiral Series
Your Chiral Separation Partner - One Platform, All Scales.
High Selectivity, High Loading Capacity, Consistent and Reproducible Results.
Welch Blossmate chiral stationary phases are designed for high-performance enantiomeric separations in analytical, preparative, and bulk purification scale. Available in both coated and immobilized polysaccharide phases, Blossmate chiral series products deliver selectivity, reproducibility, and scalability from R&D through commercial purification.

Key Advantages
- Excellent selectivity: polysaccharide-based CSPs provide superior recognition and resolution across a wide range of chiral molecules.
- High efficiency & superior separation: achieve strong peak shape, high plate count and consistent reproducibility.
- Scale-up capability: Available in analytical columns, preparative columns, and bulk media for seamless process development to production.
- SFC and HPLC compatibility: All preparative column hardware is compatible with SFC; no separate hardware required.
Modes of Use
Blossmate chiral columns and media support the full range of commonly used chiral separation modes: normal-phase, reversed-phase, polar organic, and SFC (supercritical fluid chromatography), enabling flexible method development for both polar and nonpolar targets.
Mode Switching from NP to RP
While Blossmate chiral phases can operate in both NP and RP, once switched from NP to RP, that column should remain dedicated for RP only.
Recommended conditioning before switching:
- Test the column in NP mode to confirm performance.
- Flush with isopropanol at 0.25 mL/min (4.6 mm ID) for 20 minutes.
- Then flush with methanol.
- Transition to RP using aqueous methanol or aqueous acetonitrile.
