Determination of $\beta$ -Myrcene Volatile in Mango by Quartz Crystal Microbalance Sensor

β-myrcene is one of the important terpene hydrocarbons emitted in substantial amounts from mango. In this regard, an ethyl cellulose modified quartz crystal microbalance (QCM) sensor has developed to detect β-myrcene in mango. The developed sensor exhibits a linear sensing rage of 10-1000 ppm with a sensitivity factor of 0.1 Hz/ppm. The limit of detection of the sensor was 1.68 ppm. Furthermore, the sensor is found to be selective toward the target β-myrcene analyte with respect to other volatile organic compounds present in mango with selectivity factor of 42.98% at 500 ppm. The response of the sensor was further correlated with the response obtained from the gas chromatography-mass spectrometry (GC-MS) study. The response of the prepared sensor was further validated by real mango samples. A sensor array constituting the developed sensor and the developed sensors was explored to validate the necessity of using multiple sensors for VOC detection, unlike a single sensor.
