  2. 归一化法(Normalized %) • 将样品中所有组份的含量之和定为100%。计算其中某一组份百分含量的定量方法： • 其中：xi－试样中组份I的百分含量 • fi－组份I的校正因子 • Ai－组份I的峰面积或峰高

  3. 实验内容 • 1、取1ul 含0.1%正辛烷的正己烷溶液，平行进样2次，比较正辛烷的保留时间及峰面积是否一致，并计算平均峰面积。 • 2、取1ul 含0.1%异辛烷的正己烷溶液，平行进样2次，比较异辛烷的保留时间及峰面积是否一致，并计算平均峰面积。 • 3、取1ul 含带测样品的正己烷溶液，平行进样2次，根据保留时间及平均峰面积进行定性定量。 • 实验数据请到219.229.71.114下载。
