Products and services : polymer deformulation

Deformulation (or Reversed Engineering) combines a variety of techniques such as extraction, separation, identification and quantification of individual components to build up the polymer formulation. Initial discussion with the client helps to determine the most effective analytical methods.

Depending of your request, analysis are carried out in our Lab or sent to a partner laboratory, selected and followed by PeakExpert.

Polyamides and polyolefins are our specialties.

Here are some of our capacities on deformulating aspects :

Polymer structure.

FT-IR, DSC, NMR (1H, 13C, 19F, 31P), internal and specific methods

Chemical composition ditribution of copolymers or blend - PE and PP polyolefins included

GPC-SEC with UV, FT-IR, MS, NMR couplings
Liquid chromatography in specific mode (LAC, SGIC, TGIC) with spectroscopy couplings
2D/3D chromatography, internal methods
