LCS Laboratory specializes in providing comprehensive laboratory analysis for the identification of Total Isocyanate and free residual Diisocyanates in liquid and solid polymer samples. This test is recommended for manufacturers who need to demonstrate that their products are isocyanate-free.
Our method is based on the OSHA 47 method, which was later modified for the analysis of bulk samples of cured polymers. The isocyanates are extracted from the polymer matrix using a derivatizing solution, that not only extracts the isocyanate but also derivatizes the isocyanate compounds and prevents their degradation. The resultant extract undergoes thorough analysis via High-Performance Liquid Chromatography (HPLC UV).
We offer testing for the following key isocyanates:
MDI (Methylene Diphenyl Diisocyanate)
TDI (Toluene Diisocyanate)
HDI (Hexamethylene Diisocyanate)
IPDI (Isophorone Diisocyanate)
Total Isocyanates
The typical detection limit for our analyses stands at 10 mg/kg for individual isocyanates and 50 mg/mg for Total Isocyanates.
