Guidelines for Preparative Scale and Maximum Load

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.

Guidelines for Preparative Scale and Maximum Load

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.
 

Supports Semi-Preparative and Recycle Preparative

LC-20AR

  • This solvent delivery unit can handle flow rates used in semi-preparative scale (up to 20 mL/min).
  • Using a recycle kit enables semi-preparative recycling.
 

Supports Large-Scale Preparative Fractionation

LC-20AP

  • High flow rates (up to 150 mL/min) enable highly efficient, large-scale preparative fractionation.
  • Large-scale prep solvent delivery fully supports the preparative fractionation workflow including reinjection to assess purity.
  • Combine with an FCV-200AL low-pressure gradient unit to perform gradient analysis using up to four mobile phases.

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.
