Physical and Chemical Characterisation

Physical and Chemical Characterisation

A Diverse Range of Techniques to Suit Your Reference Material

Our state-of-the-art laboratories and highly experienced scientific staff can identify and fully characterise reference standards, APIs (small molecules and peptides), impurities, powders, tablets, capsules, creams and liquids. Most often, our work involves identifying an impurity from the manufacturing process, degradation products formed during storage or the full chemical and physical characterisation of a reference material.

Using a diverse range of analytical techniques, we will identify and fully characterise the following:

  • Impurities, including genotoxic impurities
  • Degradation products
  • APIs
  • Peptides
  • Excipients
  • Salt forms
  • Polymorphs
  • Particle size and shape


Accurately Identifying Degradation Products, Impurities and Metabolites

Our dedicated GMP, MS, and NMR facility routinely performs the identification of degradation products found during stability testing, the impurities found during API and drug product testing, and the metabolites found during bioanalysis. Structural elucidation and chemical characterisation of compounds using MS, NMR and IR are carried out on a daily basis.

We use our vast knowledge of process chemistry to help determine the likely source of impurities, and we provide the process optimisation skills to eliminate them. We also have the instrumentation and synthetic capabilities to isolate or manufacture  impurities.
