Analytical services

Starting materials

Vetter offers qualification, analysis, and release of the starting materials necessary for compounding of your drug product.

In-process samples, release, and stability testing

During early clinical development, Vetter offers a wide range of analytical services designed to allow quick-release analytical testing of your clinical material. This includes chemical, biochemical, and microbiological testing for in-process samples, release, and stability testing.

Method transfer

Vetter works with you to validate compendial chemical and microbiological methods and to transfer your validated product-specific microbiological and chemical analytical methods in-house, providing a seamless transfer to clinical manufacturing and allowing you to formally release your batches. We can streamline the transfer implementation of analytical methods such as:

  • Chromatography:

    • HPLC/UPLC: Detection methods: UV/VIS, Refractive Index, Fluorescence, and CAD
    • GC and GC-Headspace: Detection methods: FID
    • IC: Ion Chromatography
  • Spectroscopy:

    • Ultraviolet-visible spectrophotometry
    • Fourier-transformation infrared spectrophotometry (FTIR)
  • Bioanalytics:

    • SDS-PAGE
    • Dot Blot and Western Blot
    • Isoelectric focusing
    • Capillary Electrophoresis (CGE, CZE, cIEF, MEKC and icIEF)
    • ELISA
  • Moisture determination: loss on drying, Karl-Fischer, titration
  • Refractometry / Refractive Index
  • Density 
  • Polarimetry / Optical Rotation
  • Melting point
  • pH measurement
  • Osmolarity
  • Titrimetric analysis: Manual & automated
  • Other standard compendial tests (USP, Ph. Eur., BP, Ph. J.)
  • Viscosity
  • Particulate matter testing (Hiac Royco, Microscope)
  • TOC
  • Conductivity
  • Oxygen content
  • Bioburden testing
  • Endotoxin testing
  • Sterility testing

Qualification and implementation of other analytical instruments is possible with individual arrangements.
