Physiochemical Tests for REACH

Befüllung eines Probengebers.

In order to register/approve substances, REACH requires they be extensively characterized using physiochemical data (among other things), which is usually determined through analytical tests.

However, this process is about more than just determining inherent material properties. It is also used to establish the substance identity, which plays a key role in choosing the right SIEF: Only registrants/importers of substances with the same or sufficiently similar identity (“sameness”) can submit a single joint dossier.

The CURRENTA Analytics laboratory for physiochemical parameters can assist you with these processes, both when it comes to determining the identity and/or sameness of your substance and identifying additional characteristics. We have a number of methods at our disposal, the use and results of which are determined and interpreted by qualified experts.

Substance identity / sameness check

  • UV/VIS spectrum
  • IR spectrum
  • MS (HPLC and GC)
  • 1H-NMR spectrum
  • 13C-NMR spectrum
