准确测量生产盐水中残留的阻垢剂浓度对于预防结垢至关重要。然而，这些阻垢剂在大多数生产条件下在亚化学计量浓度下都是有效的。用传统方法很难测量如此低的阻垢剂浓度，特别是对于无磷或低磷聚合物阻垢剂。在整篇论文中，开发了一种测定方法来确定有效的阻垢剂浓度。

The accurate measurement of residual scale-inhibitor concentration in produced brine is essential for scale prevention. However, these scale inhibitors are effective at substoichiometric concentrations in most production conditions. It is difficult to measure such low inhibitor concentration with traditional methods, especially for non- or low-phosphorous polymeric scale inhibitors. In the complete paper, an assay method is developed to determine effective scale-inhibitor concentration.
