■ Excellent resolution

-DAC column technology for semi-prep column

YMC-Actus series have been developed by applying the Axial Compression Technology to semi-prep column (20 mm i. d. and 30 mm i. d.). The column bed is compressed adequately by attaching the end assembly newly designed for YMC-Actus. It provides proper bed density (10% higher than conventional columns) and bed uniformity. The combination of technology acquired by long our experience with DAC column, the advanced technique of slurry packing, and new hardware design offers an outstanding durability and efficiency for YMC-Actus.

DAC column technology for semi-prep column

Sequential gradient test
(high-speed and high-pressure)

Column : 50 X 20 mmI.D. 5 µm
Eluent : A) water B) methanol
Gradient : 5%B-95%B
Flow rate : 50 mL/min
Pressure : ∼17MPa

-Outstanding durability and efficiency

In case of wrong packing conditions, rapid pressure change under the high-speed gradient condition degrades column performance. To examine bed stability, the column performance was evaluated after every 100 runs of the sequential high-speed gradient. YMC-Actus offers superior initial column efficiency compared to competitors. Furthermore, its excellent performance is maintained after a long series of gradient test.

-Direct scale-up from analytical to preparative

YMC-Actus has as high performance as the analytical column, and it is possible to scale up directly from analytical to preparative separation without loss in resolution.
Pro C18 RS has superior selectivity for hydrophobic compounds that differ slightly in structure and hydrophobicity. It achieved better resolution between nordihydrocapsaicin (peak 1) and capsaicin (peak 2) than competitors. Target compound was purified with high purity on YMC-Actus Pro C18 RS in direct scaling-up.
