Equally important to alternative selectivity is superior reproducibility.
Changes between different batches of stationary phases are the most common cause of customer concern.
The ACE stationary phase virtually eliminates the unpredictable adverse effects of silanol groups on HPLC separation by maintaining tight control over the entire manufacturing process and establishing stringent specifications for purity, selectivity, retention, efficiency, and asymmetry.
Therefore, as shown in the figure below, all ACE C18-PFP columns ensure absolute reproducibility between batches and columns.
Combining the available particle sizes of 3μm, 5μm and 10μm with a range of column sizes from capillary to preparative scale ensures that the method can be reproducibly scaled up or down.
The above chromatograms show excellent reproducibility when silica gel batches and silane batches are changed, and reproducible scalability when particle size and column diameter are changed.
