LCS Laboratory offers trace analysis of diisocyanates in polymers. The method is suitable for analysis of liquid as well as solid samples.

During analysis,  diisocyanates are extracted from the sample and derivatized in-situ to preserve highly reactive isocyanate from degradation. Extract is further analysed by High Performance Liquid Chromatography with UV detector.

4'4'-methylene diphenyl diisocyanate

MDI – 4’4′-methylene diphenyl diisocyanate

Hundreds of different isocyanates are produced and used by polymer industry worldwide. At the same time four most common diisocyanates represent 95% f the market:

  1. Methylene diphenyl diisocyanate (MDI)
  2. Toluene diisocyanate (TDI)
  3. Hexamethylene diisocyanate (HDI)
  4. Isophorone diisocyanate (IPDI)
