| Abstract: | Quadrupole mass spectrometer (QMS) is an instrument for effectively determining gaseous composition of fluid inclusion. The
gaseous component is extracted from inclusions with thermal decrepitation method and then determined with the sensitive QMS
instrument. The method is characterized by high sensitivity and high accuracy with the relative standard deviation (RSD,n=6) of less than 3%. It has been successfully used for analyzing fluid inclusions. The analytical results meet the requirement
of geological study. |
