在微泡蒸馏装置中，需要一种经济、快速、准确的技术来测量二元体系(乙醇-水)的汽相组成和三元体系(醋酸-丙醇-水)的液体组成。为此，使用了廉价的TGS系列气体传感器，并在一个特殊设计的腔室中进行了校准和测量。二元系拟合单参数多项式回归，三元系拟合带相互作用项的两参数多项式。两个系统的相关系数R平方均大于0.99，从而验证了这种新型传感器的实现。
A cost effective, fast, and accurate technique was needed to measure the vapor composition of a binary system (ethanol-water) and also that of a liquid composition in a ternary system (acetic acid-acetol-water) in a microbubble distillation unit. Cheap TGS-series gas sensors were used for this purpose with both calibrations and measurements carried out in a specially designed chamber. A single parameter polynomial regression was fitted to the binary system, and a two parameter polynomial with an interaction term was fitted to the ternary system. The correlation coefficient, R-squared, was found to be greater than 0.99 for both systems, thus validating the implementation of this novel sensor.
