A recent production run of TDI* has been polluted by dichlorobenzene. As a result, some end products may also be contaminated by dichlorobenzene, a chemical element that is also listed by Oeko-Tex®. This contamination of the TDI may therefore result in the emission of dichlorobenzene concentrations surpassing the limit values prescribed by Oeko-Tex®, Ikea, and specific organisations. The specialized chemical laboratory of Centexbel has a vast experience in analysing the chemicals in question and offers different tests to determine the presence and amount of dichlorobenzene, depending on the requirements according to Oeko-Tex® or to e.g. IKEA specifications through ISO 16000-9.
Determination of di- and trichlorobenze by means of extraction
- Oeko-Tex® test method: determination of chlorinated benzenes and toluenes, based on the pressurised liquid extraction with acetone. The extracts are subsequently measured by GC/MS/MS.
- DIN 54232 test method: determination of chlorinated benzenes and toluenes, based on an ultrasonic extraction with dichloromethane. The extracts are subsequently measure GC/MS/MS.
