The invention discloses a 
system for automatic separation of 
inert gases in a small gas quantity environment sample. The 
system comprises a vacuum device, a control device, a water removing device, asponge 
titanium high-temperature adsorption device, a 
gas chromatography separation device, and an 
inert gas collecting and measuring device. The vacuum device is used for enabling the 
system to be ina 
vacuum state. The control device is used for realizing 
automatic control of the whole 
inert gas separation. The water removing device is used for removing water and 
carbon dioxide from the small gas quantity environment sample gas under the control of the control device. The 
sponge titanium high-temperature adsorption device is used for removing active gases in the small gas quantity environment sample gas under the control of the control device. The 
gas chromatography separation device is used for separating 
argon gas and 
krypton gas in the small gas quantity environment sample gas under the control of the control device. The 
inert gas collecting and measuring device is used for collecting and measuring the 
argon gas and the 
krypton gas separately. According to the system for automaticseparation of the inert gases in the small gas quantity environment sample, automatic simultaneous extraction and separation of the 
krypton gas and the 
argon gas in the small gas quantity environmentsample can be realized, and problems that an 
inert gas extraction and separation is long in time consumption and complex in operation, complex samples of components cannot be processed, 
sample processing efficiency is low, and manual operation error rate is high are solved.
