    AHS-7890A Headspace Sampler auto company in the absorption of similar products at home and abroad on the basis of technical merit , has introduced the latest development of automated design , large-screen LCD display, touch keypad , digital inputs, elegant design, operation more convenient the new generation of headspace sampler .

Features
1. The metal body heating temperature control , high precision temperature gradient small ;
2. Pre- sample area , the use of personnel at the time the sample is placed more convenient operation ;
3. With the external load air conditioning systems , without any modification to the GC instrument and changes can be carried out headspace analysis . Original instrument can also be used carrier gas ;
4. By the time programmed automatically pressurized , sampling, sampling, analysis, and analysis of cleaning cleaning and other functions ;
5. The use of pressure-balanced injection technology available headspace narrow peak shape ;

6. The sample transfer tube and injection valve with automatic cleaning function, to avoid cross-contamination of different samples ;
7. For the analysis of the active substance optional elastic quartz tube as the sample delivery tube ;
8. concentration can be analyzed according to the customer at any time to adjust the level of the sample injection volume ;
9. Replace the injector needle is easy to connect all types of domestic and GC inlet.
