YMC High Performance Preparative Pre-packed Columns

  • Direct scale up from analytical and semiprep YMC-Pack columns
  • Standard column diameters: 50, 70, 100, 150, 200, 300 mm
  • Standard column length: 250, 300, 500, 1000 mm
  • Pressure resistant up to 2,000 psi
  • Matching guard columns available

Broad range of column dimensions

YMC-Pack preparative columns, packed with YMC*Gels, are available in a broad variety of column sizes to accommodate virtually any preparative separation. YMC use a high-pressure slurry technique to pack all perparative columns in optional 1,000 or 2,000 psi pressure rated hardware. Standard column dimensions range from 50 to 300 mm inner diameter and 250 to 1000 mm in length. Other column sizes will be available – please request a quotation.

Guard columns for YMC-Pack preparative columns

YMC strongly recommends the use of guard columns in order to extend column life.

Matching YMC-Pack preparative guard columns are available for all the standard column sizes in either 50, 100 or 200 mm in length, depending on their diameter.

Unique distributor-frit assembly

The flanged stainless steel hardware of the YMC-Pack preparative columns comprises a unique distributor-frit assembly that permits an efficient, uniform distribution of sample across the entire diameter of the column bed, which allows maximum sample loading via maximum utilization of the packed bed.

Similarly eluent flow is directed uniformly across the entire column diameter providing exceptional peak symmetry.

Quality assurance

All YMC-Pack preparative columns are subject to an individual chromatographic test and have to meet stringent specifications to ensure excellent column performance and column-to-column reproducibility.

A Column Test Report is included with each YMC-Pack preparative column specifying the theoretical plate number and asymmetry factor. Any of the YMC-Pack columns is guaranteed to perform consistent with its Column Test Report.

Convenient scale up

Separations developed on YMC-Pack analytical or semi-preparative columns can be directly scaled up to preparative size YMC columns. For a most convenient scale up, YMC recommends the YMC R&D Scale up Kit, consisting of a preparative column and a matched analytical column, both packed with material from the same lot.
