manufacturing qcm sensors to be used in oil industry

Abstract quartz crystam microbalance (qcm) as a very accurate and sensitive balance technique is being widely used in different industeries# the core part of this apparatus is made of very high sensitive gold coated sensor that could translate the mass loading on the sensor part to frequency changes#because of the availablity restriction and high price of this sensor, we have decided to manufacture it using a home made technique# this enabled us to modify the sensor to those which are more needed for different disciplines including the oil and gas industry# our homemade qcm sensors deliver more chemical stability, robustness and furthermore, multiple electrode arrangements can be used for differential measurements for compensating the temperature effects# coating of more electrodes with purpose of simultaneously sensing of multiple analyts is the another adavantages of this homemade sensors#recent studies have shown wide range of application of qcm in the research activties in oil and gas industry especially the most two important inorganic and organic, damages#the home-made sensor was ultimately utilized to assess the possibility of any micro scale damage; asphaltene and incompatibility related damages, in the porous rock for the low salinity water injection proposed for an oil reservoir in the south of iran#
