Novel SPME method for measuring the characteristic parameter controlling emissions of SVOCs from materials and products

摘要

Semi-volatile organic compound (SVOC) emissions can be characterized with a critical parameter, y_0, the gas-phase SVOC concentration in equilibrium with the source material. To reduce the required time and improve the accuracy of existing methods for measuring y_0, we developed a new method which uses solid phase micro-extraction (SPME) to measure the concentration of SVOC emitted by a source material placed in a sealed chamber. The experimental time was shortened from several days (even several months) to about one day, with relative errors of less than 5%.
