Introduction AHS-7910A -automatic headspace sampler is the company launched a newly developed operation more convenient , more cost-effective next-generation automated headspace sampler . Features 1. You can run up to 10 samples automatically , without staff on duty ;
2. POST, fault alarm and tips , automatic positioning tray ;
3. The computer program control , the main features are:
(1) method parameters, real-time animation display the working status , the running time ;
(2) sample area , the injection valve and sample transfer tube , three -way all alone heating temperature control ;
(3) set a good analysis program , press the Run button to automatically complete the entire sample analysis ;
(4) with a variety of extensions: dynamic headspace , purge and trap , low temperature cold trap ;
(5)can be started simultaneously GC, chromatography data processing workstation , can also be used to start the unit external program ; 4. air conditioning system has external load , without any modification to the GC instrument and changes can be carried out headspace analysis . Original instrument can also be used carrier gas ;
5. By the time programmed automatically pressurized , sampling, sampling, analysis, and analysis of cleaning cleaning and other functions ;
6. The use of pressure-balanced injection technique headspace narrow peak shape , good repeatability ;
7. sample transfer tube and injection valve with automatic cleaning function, to avoid cross-contamination of different samples ;
8. In order to complete the import gas chromatograph easier to use and accurate , the instrument comes with a variety of imported equipment for a dedicated interface for easy connection ; 9. For the analysis of the active substance optional elastic quartz tube as the sample delivery tube ;
10. The concentration can be analyzed according to the customer at any time to adjust the level of the sample injection volume ;
11. The injection needles easy to replace, can be connected to all types of domestic and GC inlet. Technical parameters 1. The sample zone temperature control range:
