MDI (diphenylmethane diisocyanate) assay

Diphenylmethane diisocyanate (MDI) is a chemical compound widely used in the manufacture of polyurethane foams, adhesives, coatings, and composite materials. Classified as a sensitizing and potentially toxic substance, its measurement is crucial for assessing exposures, verifying regulatory compliance (REACH, occupational safety), or monitoring residues in finished materials. Analysis is typically performed by high-performance liquid chromatography (HPLC) after derivatization of the isocyanate groups, often coupled with UV detection or chromatography-mass spectrometry (LC-MS). This measurement is applicable to polymers, paints, adhesives, technical textiles, or air samples collected in the workplace.

At YesWeLab, we collaborate with a carefully selected network of laboratories, most of which are certified and/or accredited (ISO 17025, COFRAC, etc.). These laboratories are chosen based on your specific needs, the matrices to be analyzed, and the required analytical techniques or methods.
If you have any particular requirements, please do not hesitate to specify them in your request: our scientific team will do everything possible to respond accurately and promptly.
Since 2020, numerous manufacturers, distributors, and engineering firms have entrusted us with the management of their analyses, sending us their samples through our digital platform.
