    摘要： Methods of chemical analysis are disclosed. In one aspect, a method may include introducing a sample into a chromatograph. The sample may include a multiple analytes having diverse sizes and chemical properties. The analytes may be present in solution with a salt. The salt may have a concentration that is higher than that of each of the analytes. The analytes and the salt may be separated with the chromatograph. The separated analytes may be introduced into an evaporative light scattering detector (ELSD). The amounts of each of the analytes in the sample may be determined with the ELSD. Other methods, including methods of analyzing plating solutions and adjusting the plating solutions based on the analysis are also disclosed, as are systems to perform such analysis and systems to adjust the concentrations of plating solutions.

    摘要翻译： 披露了化学分析方法。 一方面，方法可以包括将样品引入色谱仪。 样品可以包括具有不同尺寸和化学性质的多种分析物。 分析物可能与盐一起存在于溶液中。 盐的浓度可能高于每种分析物的浓度。 分析物和盐可以用色谱仪分离。 分离的分析物可以被引入蒸发光散射检测器（ELSD）。 样品中每种分析物的量可以用ELSD测定。 还公开了其他方法，包括分析电镀溶液的方法和基于分析调整电镀溶液的方法，以及进行这种分析的系统和调整电镀溶液浓度的系统。
