residual monomers

We offer you the selective determination of free residual monomers in various plastic products.

This means that we enable you to make a statement about free monomers in your sample materials with the help of effective sample preparation and subsequent quantification. In this way, we support you in the quality assurance of your products.

For you, this means security with regard to the strict quality and safety requirements for your plastics production.

How can we support you?

Our techniques:

• Specific migration
• GC-MS/MS
• LC-MS/MS
• HPLC-UV
• GC-FID/-ECD

We can offer you the analyses under research conditions / ISO 9001 or DIN EN ISO/IEC 17025 conditions.

Examples for sample matrices:

• Plastic products or prepolymers based on polyurethane (determination of free residual isocyanates
• Plastic products based on polycarbonate (determination of monomeric bisphenol A)

For the manufacture of many plastic products, reactive starting materials are used that are regulated by the authorities due to their sensitizing or health-hazardous characteristics (e.g. diisocyanates, bisphenol A).

CURRENTA Analytik has been carrying out residual monomer analyses of various materials for many years. For this purpose, CURRENTA uses its broad portfolio of methods, from sample preparation to analysis by means of HPLC-UV, LC-MS/MS, GC-MS/MS and others.

CURRENTA Analytik already has established methods for the determination of various residual monomers in accordance with DIN EN ISO/IEC 17025 specifications (e.g. bisphenol A in polycarbonate and diisocyanates in polyurethane-based prepolymers).

If required, we can develop analytical methods for residual monomer analysis tailored to your specific needs and offer you matrix-specific validation and subsequent measurement of your products in accordance with DIN EN ISO/IEC 17025 specifications in the concentration range required by the regulatory authorities. Thus we support you in complying with official quality and safety requirements.

Application example:

Quantification of MDI, TDI, HDI and IPDI in various matrices by LC-MS/MS according to DIN EN ISO/IEC 17025 specifications in the regulatory concentration range.

Quantification of bisphenol A in polycarbonate by means of HPLC-UV or LC-MS/MS according to DIN EN ISO/IEC 17025 specifications in the regulatory concentration range.
