Abstract :
A high sensitivity chloroorganics detector of the crystal-oscillator type has been developed. The advantages of this type of detector are the ability of continuous monitoring and adoption of a quartz crystal microbalance (QCM) method. Chloroorganics are detected by oscillation frequency change due to the weight of the absorbed gas. By this experiment, it has been understood that the identification of the sample is also possible at the same time as measuring the concentration. The measurement is done by comparing the measured results by two or more QCM covered with different lipid within the range of 1000 ppm
