YMC-Pack
YMC’s classic column phases.
The YMC-Pack Series includes multiple phases and modes of separation. These products are used in countless methods around the world, a testament to our longstanding reproducibility.
The high-strength “HG” version of the resins allow direct scale-up with particle sizes of 10 µm and above.
