Potash (KCl) production is a large and economically significant industry in Saskatchewan. Along with KCl, potash ore contains large quantities of Halite (NaCl). The chemical and physical similarity between these two minerals make them difficult to distinguish from each other in the ore. This leads to problems maintaining a consistent feedstock to the mill. A similar problem arises in determining the relative concentrations of KCl and NaCl in solution. The current state of the art is to use the radioactive decay of the naturally occurring K40 isotope, or off-line X-ray techniques. The equipment required for these approaches is expensive and not conducive for on-line monitoring and process control.

钾肥生产在萨斯喀彻温省是一个巨大的、具有重要经济意义的行业。除氯化钾外，钾矿还含有大量的盐酸盐(氯化钠)。这两种矿物在化学和物理上的相似性使它们很难在矿石中相互区分。这就导致了向磨机保持一致的原料的问题。在测定溶液中氯化钾和氯化钠的相对浓度时也出现了类似的问题。目前的技术水平是使用自然产生的K40同位素的放射性衰变，或离线X射线技术。这些方法所需的设备昂贵，不利于在线监测和过程控制。
