Columns/YMC*Gel
Particle size of preparative spherical packing material is 10µm, 15µm, 20µm, 50µm, 75µm, and 150µm. Their quality of all sizes of products is strictly controlled. YMC S-50 gel (particle size 50µm) is useful for preparative chromatography because of their moderate particle size and good cost performance. Characteristics of YMC S-50 gel are as follows:
- YMC S-50 gel is the perfect spherical packing material with particle size 50µm, pore size 12nm (120Å).
- YMC S-50 gel is packing material with a narrow particle size distribution, so you can get a high column efficiency even packed by tapping method.
- YMC S-50 gel is a high performance and cost effective product.
- YMC S-50 gel is effective for both semi-preparative and industrial separations.
- YMC S-50 gel is suitable for preparative isolation using YMC pressure resistant glass columns.
High column efficiency can be obtained even when tapping method is used for packing.
Comparison of the performance of a column packed with YMC S-50 gel by tapping method, with a column packed with YMC S-50 gel by slurry method. You can get the same column efficiency by easy tapping or by slurry packing.
