• Selective Determination of Pentafluorobenzyl Ester Derivatives of Carboxylic Acids by GC Using Microwave Plasma and Mass Selective Detection

  A highly selective, sensitive method for determination of carboxylic acids in water has been developed that is based on fluorine-selective gas chromatography (GC) detection of pentafluorobenzyl ester derivatives. The atmospheric-pressure helium microwave-induced plasma detector is well suited for fluorine-specific detection of these derivatives, which were well resolved by capillary GC and displayed a characteristic fragmentation behavior when examined by GC-mass selective detection. For demonstration purposes, a number of carboxylic acids, ranging from C₁ to C₂₀, were examined and found to be derivatized with yields greater than 90%, and a sample of creek water was examined for its carboxylic acid content.

  已开发出一种基于氟选择性气相色谱（GC）检测五氟苯甲酸酯衍生物的高度选择性、敏感的水中羧酸测定方法。大气压氦微波诱导等离子体检测器非常适合氟特异性检测这些衍生物，这些衍生物通过毛细管GC得到很好的分辨，并在GC-质谱选择性检测时表现出特征性的碎裂行为。为了演示目的，检测了一系列从C1到C20的羧酸，并发现它们的衍生产率大于90％，并对一份小溪水样品进行了羧酸含量检测。
