Abstract: | New possibilities for using the equation that takes into account the nonlinear variation of parameters of the reference n-alkane scale for the calculation of retention indices of polar substances at different modes of temperature programming were considered. The advantages of this equation over the linear scale used traditionally were demonstrated in relation to C3—C11 alkan-1-ols. The equation appears to have considerable promise regarding the search for the equivalent isothermal index. |
