Application Notes

HPTLC is the method of choice for many analytical tasks - a broad range of Application Notes is available for download. Registered users can download the Application Notes for free.

CAMAG Laboratory develops and validates HPTLC methods for the identification of botanical raw materials and finished products. By following these methods reproducible results are guaranteed.

These documents are part of the appendix of the paper Validation of High-Performance Thin-Layer Chromatographic  Methods for the Identification of Botanicals in a cGMP Environment by Eike Reich, Anne Schibli, and Alison DeBatt (Journal of AOAC 91(1) 2008). This paper provides a summary of a project that aimed at:

  • development and validation of 10 HPTLC methods for identification of botanical raw materials
  • elaboration of a general concept for validation of such methods
  • proving that their validation is possible and necessary with respect to cGMP
  • providing to the botanical industry guidance in establishing practical and meaningful methods for quality assurance.
