Figure 1From: Microbial volatile organic compound emissions from Stachybotrys chartarumgrowing on gypsum wallboard and ceiling tileExperimental setup. The experimental setup allows for easily introducing the sorbent tubes into the sample loop without the need to open the growth chambers. A miniature pump draws the headspace from the chambers into the sorbent tube. The sample loop continues to a rotameter, where airflow is measured and is then transferred back into the growth chambers, thus providing a completely enclosed sample trajectory.Back to article page
