WebJul 15, 2010 · In general, the thermal desorption method showed the best repetitivity and recovery and the lowest limit of detection and quantification for all target compounds. Because of its lower sensitivity, the solvent extraction method needs the preconcentration of large sample volumes of air (720 L vs. 2.64 L for the thermal desorption method) to yield … WebSolvent desorption (SD) of air samples collected using sorbent tubes is a long established analytical procedure. However, in the 1980’s an alternative method, thermal desorption … ctenanthe types
