当离子交换色谱柱与梯度洗脱系统结合并连接到 Technicon AutoAnalyzer 时，可以对洗涤剂中的缩合磷酸盐混合物进行快速常规分析。这种技术的组合提供了一种相对无干扰的自动方法，因此不需要对样品进行初步处理。该方法的准确度一般在主成分含量的±3%以内；可以检测到低至百分之几的微量成分。
Rapid routine analysis of condensed phosphate mixtures in detergents is possible when an ion exchange chro-matographic column is coupled with a gradient elution system and connected to the Technicon AutoAnalyzer. This combination of techniques provides an automatic method which is relatively interference-free, and, consequently, no preliminary treatment of samples is required. The accuracy of the method is generally well within±3% of the amounts of the major components; minor components can be detected down to levels of several hundredths of a per cent.
