Impurity isolation & sample purification

 

Utilising in-depth expertise in preparative chromatographic and spectroscopic techniques, RSSL's impurity isolation and sample purification services help you meet stringent regulatory expectations and solve complex analytical challenges across the drug development lifecycle. 

 

Unknown impurities can arise at all stages of the pharmaceutical R&D lifecycle, from drug discovery through to commercialisation. Identifying and eliminating these impurities is essential to help protect patient safety. RSSL’s expertise in isolating and identifying impurities enables us to play a key role in helping you to research, develop and manufacture high quality pharmaceutical products.

    Impurity isolation and identification

    Our expert scientists use a wide range of state-of-the-art techniques to isolate, purify, and characterise pharmaceutical impurities at trace levels, even in complex matrices. Preparative scale isolation is first carried out using chromatographic techniques and post-purification treatment, such as freeze drying. Advanced spectroscopic techniques can then be employed to identify the impurities of interest.

     

    Once the impurity has been identified, we also offer further scale-up for the isolation of larger quantities of impurities for use as reference materials. This combination of orthogonal techniques ensures the highest possible purity and accurate characterisation of isolated compounds.
