Displacement chromatography coupled with SACHEM’s Expell™ displacers makes the technique simple enough for every day use.

Check out the results below with SACHEM’s Expell™ Q1 on Tosoh’s TSKgel Super Q column. 

Diagram A is the displacement chromatography trace. 
Diagram B is the fraction analysis of the displacement chromatography train. 
Finally, Table C is the recovery and purification data from this displacement separation.

Diagram A: Displacement Chromatography Trace at 280 nm (protein + displacer) and 312 nm (displacer only)

Diagram B: Fraction Analysis Corresponding to the Displacement Chromatography Train Above

Diagram B demonstrates the increased capacity and purity that is attainable using displacement chromatography versus elution chromatography.

Table C: Resulting Recovery and Purity Data from Fraction Analysis
