摘要: Abstract The technique of thermal desorption (TD)-GC/MS was evaluated for the measurement monoterpenes in indoor air. validation strategy intentionally oriented towards routine use and reliability method rather than extreme performance. For this reason, by accuracy profile chosen. procedure, which is based on concept total error (bias + standard deviation), guarantees that a known proportion future results obtained with will be within acceptance limits. all compounds tested present study, α-pinene, α-terpineol, β-pinene, d-limonene, Δ3-carene, camphene, 1,8-cineole, p-cymene, linalool, but not case carvone, procedure established at least 95% would ±15% limits validated over whole defined concentration range. Other parameters, such as selectivity, recovery, repeatability, stability molecules interest effect temperature, were also determined. performance described finally analysis air from new timber frame constructions.
