Migration Tests and Residual Monomer Analysis
For many years, CURRENTA Analytics has been carrying out migration tests on materials (plastics) intended to come into contact with food. To do so, CURRENTA uses a variety of methods from its wide-ranging portfolio – from simple gravimetric determination in global migration to trace methods, e.g. using LC-MS/MS or GC-MS/MS for the specific migration of monomers or additives.
CURRENTA Analytics has an arsenal of established methods and procedures at its disposal, but can develop specific analytical methods for the particular migration if necessary, taking into account your specific needs. The frequently required detection limits in the range of just a few μg/kg (ppb) can usually be achieved using state-of-the-art combination techniques, such as GC-MS/MS and LC-MS/MS.
At CURRENTA Analytics, we conduct migration testing and analyses in accordance with REGULATION (EU) No. 10/2011 (often referred to as the “Plastics Implementing Measure” or “PIM”). This means we use the prescribed food simulants, such as 10% ethanol, 3% acetic acid and vegetable oil (food simulants A, B, C, D1, D2). For solid foods, we use poly(2,6-diphenylphenylene oxide) as a surrogate (food simulant E) during migration. After the migration experiment, we analyze the poly(2,6-diphenylphenylene oxide) used either through classic extraction or through thermal desorption and GCMS.
We’re happy to work with you prior to testing to coordinate the contact conditions for your materials. When it comes to the requirements placed on analytics, we follow the “Note for Guidance for Food Contact Materials” of the European Food Safety Authority (EFSA) if you require a food contact notification.
We can also simulate other contact conditions beyond the scope of the EU regulation at your request.
Here are some example applications for specific migrations:
- Monomers, additives and residual solvents from polycarbonate
- Monomers, additives and residual solvents from ABS
- Monomers, additives and residual solvents from polyester
- Monomers, additives and residual solvents from polyamide
- Additives and residual solvents from polyolefin
If requested, we can use the migration tests to check whether your food contact material meets the requirements of Regulation (EU) 10/2011 or can be used to manufacture toys.
