Method development & validation

At RSSL, we have the knowledge and capabilities to support analytical method development and validation for a wide range of formulation types throughout the drug development lifecycle.

 

As companies focus on achieving ever shorter timescales for transitioning from drug discovery to market application, it is vital that a tailored and pragmatic approach is adopted for both method development and validation.  

 

Successfully developed and validated analytical methods can reduce overall turnaround times and underpin a robust product. By starting with the endpoint in mind, methods can be developed to have flexibility built in during the early stages. This can enable seamless translation from API to drug product, potentially reducing costs throughout the product lifecycle. 

 

Our cross-laboratory, multi-disciplinary approach, combined with our exemplary customer focus and communication, make us an ideal partner for method development and validation activities.

Method development

 

Drawing on over 30 years of experience working with a diverse client base and a multitude of different dosage forms, we can support you in developing robust, fit-for-purpose methods appropriate for analysis of potency, purity, physical characteristics and stability. 

 

Our experienced team offers a wealth of knowledge and advice on areas ranging from sample preparation and extraction techniques to regulatory requirements and specialised methodology. 

Method validation

 

Following successful method development, we can perform phase appropriate method validation according to the ICH Q2 (R1) recommendation for the analytical procedure. We can also validate methods developed by other laboratories.

 

Additionally, we can perform a gap analysis of previously validated methods to ensure they meet the current guidelines and maximise the likelihood of a successful regulatory filing. All our work is conducted according to the method parameters set out by the ICH guidelines.

  • Ultra-Performance Liquid Chromatography (UPLC) with Diode Array (DAD) 
  • High-Performance Liquid Chromatography (HPLC) with UV. Diode Array (DAD), Evaporative Light Scattering Detector (ELSD) or Fluorescence Detection (FLD) 
  • Preparative HPLC  
  • Fast protein liquid chromatography (FPLC) 
  • Gas Chromatography with Flame Ionisation Detection (GC-FID) 
  • Gas Chromatography-Mass Spectrometry (GC-MS) 
  • Ion Chromatography with Conductivity Detection (IC-CD) 
  • High-Performance Anion Exchange Chromatography with Pulsed Amperometric Detection (HPAEC-PAD) 
  • Liquid Chromatography-Mass Spectrometry (LC-MS) 
  • Atomic Absorption Spectroscopy (AAS) 
  • Inductively Coupled Plasma Mass Spectrometry (ICP-MS) 
  • Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) 
  • Laser Diffraction (Mastersizer 2000 and 3000)
