Is your substance a polymer according to REACH definition?

Gel Permeation Chromatography (GPC) can answer the question whether a substance is a polymer according to REACH definitions or not. At LAUS we offer the analyses as described in OECD 118 and OECD 119:

• Low Molecular Weight Content
• Number-Average Molecular Weight
• Molecular Weight Distribution

and a full evaluation of the results regarding the REACH criteria for polymers:

• 3M+1 rule: Polymer molecules contain a sequence of at least 3 monomer units, which are covalently bound to at least one other monomer unit or other reactant
• > 50 % by weight consists of polymer molecules
• < 50 % by weight of polymer molecules present the same molecular weight

We have the experts in house. Contact us for more information!
