| Abstract: | A variety of volatile organic compounds(VOCs) associated with wood-based products were determined by combining the results from auto thermal desorption(ATD) and gas chromatography/mass spectrum(GC/MS).A lower sampling flow rate should be employed to decrease the benzene penetration into the Tenax TA tube to improve the accuracy.The results showed good repeatability and stability when this method was used. |
