Preparative Purification Liquid Chromatograph
Excellent System Expandability
Solvent Delivery Unit Accommodates a Wide Range of Recovery Volumes
Guidelines for Preparative Scale and Maximum Load
The figure at right shows the guidelines for total component capacity with a 250 mm long column when the target component is highly soluble in the mobile phase, separates from impurities, and ions are suppressed. For isocratic elution, in principle, the total component capacity is proportional to the column volume.
LC-20AT
This solvent delivery unit can handle flow rates ranging from those used in analytical scale to those used in semi-preparative (up to 10 mL/min).
High-precision analysis is possible even in the semi-micro flow-rate range.

Shim-pack Scepter Columns
- Excellent stability & performance using a wide range of LC conditions -
Shim-pack Scepter LC columns, which are the next generation organic silica hybrid based columns, are designed for stability and performance in a wide range of mobile phase conditions. With different chemistry characteristics, Shim-pack Scepter columns are effective for method development/scouting under conditions that may compromise traditional silica based columns.
With different particle sizes (1.9 μm, 3 μm, 5 μm) and different column dimensions, Shim-pack Scepter LC columns are fully scalable between UHPLC, HPLC and preparative LC, making method transfer seamless between different laboratory instrumentation.
