| 摘 要： | 气相色谱测定岩石、矿物中的H2O-和H2O+1]是将气相色谱技术引入岩矿分析中一次成功尝试,它为岩矿分析仪器化自动化开辟了一条新途径,是测定H2O-和H2O+的新方法。它的优点是明显的,灵敏、简便、快速、用样量少,极适宜于微量单矿物中水的测定。但此法用峰高定量,水峰拖尾又较严重,影响方法的精度和准确度;一次称样同时测定H2O-和H2O+,温度忽上忽下,颇费时间;为了确定稳定空白值,对器皿的处理和放置时间的要求苛刻。由于这些问题,使方法的推广受到限制。

| Abstract: | The method determinating water in rock and mineral by gas chromatograph has some advantages,such as wide scope of analysis,high sensitivity,simplicity,accuracy,rapidity,etc.and contributes to automatization of analysis of rock and mineral.The instrument used by authers was modified to make the water peak narrow.Some measurements were taken to expand the range of analysis and to improve it’s speed,precision and accuracy,including the use of integrated peak without substructing blank for quantitative analysis and external standard for calculation.This method was used in our laboratory for one year and more.The practice proved that the method could be used instead of classical analytical method. |
