Introduction
DAC (Dynamic Axial Compression) is recognized as the optimal column packing technique for preparative chromatography. It ensures reliable separation performance in large-scale column chromatography, especially for columns with an inner diameter over 100 mm. Featuring easy operation, high safety and leak proof design, it is widely used in the preparation of peptides, amino acids, insulin and natural products.
QuikSep DAC columns allow self-packing of media with high efficiency, excellent column performance, good reproducibility and long service life. They can be packed with fine 10 μm packings to achieve analytical grade column efficiency. The unique distributor and collector design further improves separation. It is widely applied in natural product extraction, synthetic drugs, protein and peptide purification, and serves as a key instrument for modernization of traditional Chinese medicine.
Feature
1.?Excellent column efficiency & reproducibility: Dynamic axial compression enables stable packing of 10 μm media, delivering high efficiency, resolution and repeatability.
2.?Safe operation & easy maintenance: Reliable sealing prevents leakage and contamination; supports self-packing with easy maintenance and long service life.
3.?Precise, stable & durable: Premium key components, unique distributor and wall treatment ensure stable long-term operation and compact column bed.
4.?Wide compatibility & flexible use: Works with various packings, scales from lab to production, ideal for columns >100 mm ID.
5.?Customizable & configurable: Flexible detection and collection modules for tailored purification in natural products, peptides and pharma.
