Samples of 5 VOCs were collected by private air sampler (Sibata, Japan) with a Tenax sorbent tube (1/4′′×20 cm stainless steel, Supelco, USA). Samples had been collected over a period of half-hour and sampler flow was 0.2 L/minute. After the pattern was collected, the sorbent tube was put into Swagelok, sealed with Teflon caps on both ends and refrigerated at lower than -75°C until evaluation.
