Determining the Optimum Exposure and Recovery Periods for Efficient Operation of a QCM Based Elemental Mercury Vapor Sensor

Figure 6

(a) Sensor’s dynamic response towards 365  of Hg⁰ vapor exposed for 30 minutes with desorption time of 70, 90, and 120 minutes and (b) sensor’s adsorption and desorption magnitude towards 30 minutes of Hg⁰ vapor exposure while the desorption period was varied between 10 and 120 minutes. The response magnitudes of the final cycle of each event are plotted.
