合成了几种纯的甲基三烷基氯化铵，并将其作为液膜电极中的Cl−选择性组分进行了评价。这些基于PVC的电极的选择性、稳定性和寿命已被证明对所使用的铵化合物和增塑剂的组合敏感;膜组合物已被优化用于血清中的Cl−活性测量。该系统应用于血清的固有适用性得到了重现性的证实，只要避免与校准水溶液接触，其重现性与常用的Cl−分析技术相比就很好。
Several pure methyltrialkylammonium chlorides were synthesized and evaluated as Cl−-selective components in liquid-membrane electrodes. The selectivities, stabilities and lifetimes of these PVC-based electrodes have been shown to be sensitive to the combination of ammonium compound and plasticizer used; the membrane composition has been optimized for Cl−-activity measurements in blood serum. The inherent suitability of this system for applications to blood serum is borne out by the reproducibilities achieved, which compare well with those of popular analytical techniques for Cl−, as long as contact with aqueous calibration solutions is evaded.
