ABSTRACT BODY: Abstract: We reported recently that the photoionization detector (PID) with a 10.6 eV lamp responds to mercury (Hg) with detection limits of 10 ppb. The PID is a non-specific method for Hg since it also has a strong response to VOC’s. Other non-specific methods like UV absorbance and atomic fluorescence use a gold pre concentrator (GPC) to collect Hg by forming a Au/Hg amalgam at room temperature, pu
