自地气法引入我国以来,在地气采集方法由被动法到主动法、地气捕集剂由固态泡塑捕集剂到液态捕集剂、实验分析测试仪器和样品处理方法上都有了长足的发展。使得实验所得数据的重现性和准确性都得到了显著的提升。通过对现行地气捕集和样品处理方法进行改进,加大地气的抽取量和捕集剂量,延长地气进入捕集器时与捕集剂的接触时间,提高捕集效率。
Since the gas law was introduced to our country, the method of gas collection from passive to active method, the gas collector from the solid state plastic foam collector to the liquid collector, experimental analysis of test equipment and sample processing methods have Long-term development. Making the experimental data reproducibility and accuracy have been significantly improved. By improving the existing methods of ground gas capture and sample processing, increasing the amount of ground gas extracted and the amount of trapping agent, the contact time with the trapping agent when the ground gas enters the trapper is prolonged to improve the collection efficiency.
