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

Figure 4

(a) Sensor’s dynamic response toward Hg⁰ vapor concentration of 365  exposed for 30 and 120 minutes; (b) 30 and 40 minutes; and (c) 90 minutes and 120 minutes, all having a constant recovery time of 60 minutes. (d) Sensor’s response magnitude towards 365  of Hg⁰ exposed for 10 to 120 minutes with a recovery time of 60 minutes.
