岩石矿物中的结晶水和二氧化碳的测定通常用双球管灼烧和直接吸收法。这两种方法不但称样量多、分析时间长,而且劳动强度大、精度低。目前大多教已采用仪器分析法。 我们认为凯第尔电解法仪器,结构简单,操作方便,价格低廉,而且精度较高。因此研制以铂—五氧化二磷—水体系来测定微量水和二氧化碳分 Crystalline water and carbon dioxide in rock minerals are usually measured by double-bulb ignition and direct absorption. These two methods not only call the sample volume, analysis time, and labor-intensive, low accuracy. At present, most teaching has adopted instrumental analysis. We believe that the kitchel electrolysis equipment, simple structure, easy operation, low prices, and high accuracy. Therefore, the development of platinum - phosphorus pentoxide - water system to measure trace water and carbon dioxide points
