Studies have shown that fluids,especially gases plays a very important role in volcanic activity and earthquakes,and that analyzing and testing ingredients of emergent gas thermal spring have important scientific significance and monitoring value.This paper,by theoretical summary of the observation practice of determination of composition of emergent gas from the thermal springs in Tengchong volcano area using gas chromatography in the Tengchong Volcano geochemistry Observatory,systematically introduced the rapid determination method of ingredients of emergent gas thermal spring by gas chromatography.The results show that,SP3400-type gas chromatograph series has a number of advantages.Through a rational instrument setting,parameter configuration,standardized maintenance and analysis operations,SP3400-type gas chromatograph can rapidly and accurately analyze concentration of the conventional components such as He,H_2,O_2,N_2,CH_4,CO_2 of emergent gas from thermal spring.The relative deviation of analysis of total of these ingredients is only 1.89%,that of the CO_2 component,only 2.18%,He,H_2,ppm-level content,only 10.24% and 11.44% respectively,indicating the analysis and testing results of SP3400-type gas chromatograph have a very high reliability and accuracy.SP3400-type gas chromatograph is of ideal instruments for rapid determination of the conventional components of emergent gas from thermal springs,and can be promoted to use in volcanic and seismic monitoring stations.
