Liquid chromatography/mass spectrometry (LC/MS) has been applied to the analysis of triphenylboron, which has been produced as a substitute for organotin compounds, in water. Although commercial triphenylboron compounds are produced as pyridinyl complexes, the chemical form in water is supposed to be mainly triphenylboron after liberating pyridine. The triphenylborons were extracted from water with an Empore C18 extraction disk under acidic condition, and the extracts were introduced directly into a liquid chromatograph-mass spectrometer equipped with a negative ion electrospray ionization interface. Identification of the compounds was performed with specific ions produced from the triphenylboron, and a quantitative analysis was carried out using the peak areas. The average recoveries from distilled water, seawater and river water at 0.30 ng/ml were 92.3, 100 and 85.3%, respectively. A detection limit of 0.023 ng/ml for triphenylboron was achieved.
液相色谱/质谱联用（LC/MS）已应用于水中三苯基硼的分析，三苯基硼是作为有机锡化合物的替代品生产的。尽管市售的三苯基硼化合物是以吡啶基配合物的形式生产的，但在水中释放吡啶后，其化学形态预计主要为三苯基硼。在酸性条件下，用Empore C18萃取盘从水中萃取三苯基硼，萃取物直接引入配备负离子电喷雾电离接口的液相色谱-质谱仪中。通过三苯基硼产生的特定离子对化合物进行鉴定，并使用峰面积进行定量分析。在0.30 ng/ml时，从蒸馏水、海水和河水中的平均回收率分别为92.3%、100%和85.3%。三苯基硼的检测限达到0.023 ng/ml。
