ANALYSING METHOD OF C1——C12 PNA COMPONENTS IN ROCKS
-
摘要: 本文介绍研究岩石中C1-C12PNA组份的一种分析方法.该方法在90-100℃进行真空脱气,脱气条件严格探制,始终保持一致,不但脱气率高、重现性好,而且分离的组份不失真.测定结果具有代表性.另外,在优选条件下,实测C1-C5校正因子,将HP5880C5-C0PNA程序收进为C1-C12PNA程序.这就充分利用了仪器功能,是目前研究C1-C12PNA组份的一种较为有效的分析方法.Abstract: A C1-C12 PNA analysis method for source rock study is introduced.the method involved vacuum degasification under 90°-100°C.The condition of degasification is constant,and strictly controlled.The degassing rate is high,with no distortion for separaed components.The results is proved to be representative.Meanwhile C1-C5 calibration factors are determined under optimum condition.C5-C10+ PNA program of HP5880 GC is worked out by revision of the original C1-C12 PNA program.Thus,the full usage of the instrument is made.The method is effective for C1-C12 PNA component study.
