With this definition of the partial molar excess Gibbs free energy and the activity coefficient, the fugacity of a species in a liquid mixture can be computed from: (55)f¯iL(T,P,x)=xiγi(T,P,x)fiL(T,P) where the fugacity of the pure component is equal to the vapor pressure of...

Their mass spectra highly resembled those of normal alditols, but in each case the spectra also contained intense ion peaks with the m/z values (e.g. 243) that are unusual for trimethylsilylated normal alditols. The disaccharide-type sugars and “unusual polyhydroxy compounds” eluted before ...
A liquid chromatography method using UV detector and ESI mass spectrometry has been developed by which the mean relative molecular mass of sodium alkylbenzenesulfonates can be determined without any pre treatment. 直接用高效液相色谱法将烷基苯磺酸钠按碳数分布分离 ,计算其平均相对分子质量 ;用紫外检测...
