Preparative HPLC Columns and DAC Columns

SpiritTM Preparative HPLC columns from AAPPTec are capable of purifying grams of crude peptide.  Spirit preparative HPLC columns provide the same high performance as Spirit Analytical and semi-preparative columns.

For larger, production scale purification, AAPPTec provides Dynamic Axial Compression (DAC) columns.  DAC columns provide the following advantages:

  • High performance packing in a minimum amount of time.
  • Constant pressure from the piston maintains a consistent bed whether the column media shrinks or swells.
  • Constant pressure from the piston reduces or eliminates channeling.
  • Provides highest possible resolution and sample distribution.
  • Provides longer column life with high performance.
