浩瀚救生筏专用钢瓶气中组成测定气相色谱仪GC7990

Fertilizer plant production of carbon dioxide mixed with pure nitrogen, and adding trace ethanol and irrigation made of marine liferaft special cylinder can be used as marine lifeboat automatic gas source equipment. The addition of traces of ethanol to the cylinders of liferafts increases the vaporization temperature of the carbon dioxide in the cylinders to keep the air flow stable during an instantaneous filling and to prevent the airflow from being blocked by the condensation of carbon dioxide. Process production, life-saving valve cylinder mixed with carbon dioxide, nitrogen and trace ethanol content ratio must be strictly controlled.
In order to accurately determine the content of various components and trace impurities, Tengzhou Xiangying Analytical Technology Co., Ltd. using GC7990 gas chromatograph, the results were satisfactory.
化肥厂生产的二氧化碳与纯氮气混合,并加入微量乙醇而灌制成的船用救生筏专用钢瓶可作为海洋救生艇中自动充气源设备。救生筏专用钢瓶中加入微量乙醇可提高气瓶中二氧化碳的汽化温度,使其在瞬间的充气中保持气流的稳定,防止因二氧化碳的冷凝阻塞气流。工艺生产中,救生阀专用钢瓶混装的二氧化碳、氮气及微量乙醇的含量比例必须严控制。
为了准确测定各组分及痕量杂质的含量,滕州市翔鹰分析技术有限公司采用GC7990气相色谱仪，结果满意。
