Using some polar solvents, contact angle, polar solvents commonly used sequence: the contact angle of water (max)> formamide> acetonitrile> methanol> ethanol> propanol> acetone> dioxane> tetrahydrofuran> methyl ethyl ketone> n butanol> ethyl acetate> ether> isopropyl ether> dichloromethane> chloroform> dibromoethane> benzene> CTC> Carbon disulfide> cyclohexane> hexane> kerosene (minimum). You can try this order Then you try cyclohexanone it, SDC-200 contact angle, his volatility is still relatively small. bead height / width method using equations to fit the round shape of the droplet summarize, thus accounting of the contact angle. Since this approach assumes that the droplets (cross-section) is part of a circle shape, so its scope is limited to spherical or near to spherical droplets. Due to the influence of gravity, strictly speaking, the shape of spherical droplets are contrary: the degree of violation of the droplet volume increases with the increase; in the same volume, the larger the specific gravity of the liquid, SDC-500 contact angle, The smaller the surface tension, SDC-100 contact angle, the greater the violation of ups and downs. Under normal circumstances, on volume of less than 5 microliters of water droplets, which suffered the impact of gravity on the shape is considered small enough to be negligible, this approach accounts available at the moment. Speaking after the literature measuring the height and width of the droplet contact angle of approach to accounting that is the round could have been the easiest method to use. The above mentioned method Conic round Act would have been included, because the circle of a quadratic equation only exception.
