Dew point measurement for organic vapor mixture using a quartz crystal sensor

Detection of bubble and dew point using optical thin-film interference

“…Syntheticvisual techniques are the most common methods, involving a pressure-volume-temperature (PVT) cell with a visualization window which allows direct observation of phase transition as a function of cell pressure and temperature [10,11]. Synthetic-nonvisual experimental methods have also been developed, using acoustics [12,13], quartz sensors [14][15][16] and infrared spectroscopy [17]. Microfluidic-based PVT devices were developed to measure physical properties such as diffusivity of immiscible fluid mixtures, showing orders of magnitude improvement in speed and sample volume [18,19].…”

In-Line Measurement of Water Contents in Ethanol Using a Zeolite-Coated Quartz Crystal Microbalance

“…The QCM application uses the frequency variation to detect the changed loading. The variation of mass loading was employed to detect the dew point of organic vapor condensing on an electrode surface [ 15 ]. The variation of micro-rheology was also used to determine the kinetic rate of photopolymerization [ 16 , 17 ] and the variation of the thermal properties of polymers [ 18 ].…”

On-line measurement of monomer concentration in UV photopolymerization using a quartz crystal resonator

“…For example, the resonator was applied to monitor gas-phase polymerization [17], crystallization [18][19][20] and condensation process involving phase change [21]. In photopolymerization, the resonator was employed in an on-line monitoring the UV photopolymerization [22] and in measuring the surface adsorption of surfactant used for the surface modification of glycidyl methacrylate [23].…”
