Abstract

Use of hydrophobic membrane filters is shown to effectively reduce the interfering moisture level in the detection of SO2 in air at the parts per billion range. Quadrol is used as a sensitive coating on piezoelectric crystal detectors in a flow system.

用涂层压电晶体探测器测量空气中的二氧化硫。
使用疏水膜过滤器被证明可以有效地降低在十亿分之一范围内检测空气中二氧化硫的干扰水分水平。在流动系统中,Quadrol被用作压电晶体探测器的敏感涂层。
