Extremely Precise, Assay Method

This Assay Method for a common Ibuprofen formulation demonstrates Reproducibility and Robustness as the Figure below shows an overlay of four Chromatograms with different Columns lots (%RSD < 1).

An important aspect of Column Selection for a Method is that the Retention behavior is consistent across numerous manufacturing batches. This is especially crucial once a Method has been validated and is in routine use.
