AHS-50 Automatic Headspace Sampling Device Tester for Test the Volatile Component of the Sample
principle
The simple principle of AHS-50 automatic headspace sampling device is that the sample to be tested is placed in a closed container, and the volatile components of the sample to be tested are volatilized from the sample matrix by heating up to achieve a balance in the gas-liquid (or gas-solid) phase, and the upper gas is directly extracted for chromatography. Thus, the composition and content of volatile components in the sample were detected.
1. The rotary valve switching multi-dimensional gas path sampling system overcomes the disadvantages of domestic six-way and 10-way valves, such as short service life and inability to withstand high temperature
2. The gas path process design is very simple, reliable, conducive to leakage prevention, greatly improve the work efficiency
3. Inert treatment technology is adopted in the gas path and sample valve that the sample passes through
4. Optional gas path (EPC electronic pressure control), digital display is more intuitive. It can realize automatic gas path system leak detection and obstacle alarm
5. By adjusting the injection time, the sample has been analyzed for different concentrations
6. For various standards, can store 10 methods
7. Full color screen display, friendly interface, touch operation, can be quickly and easily mastered, the whole tracking display operation process, set parameter value and real time value
8.4 pre-heating stations can realize circulating heating and improve analysis efficiency
9. Expand the scope of services: (1)To provide customers with experimental equipment solutions, technical consultation or co-construction and sharing of chromatographic analysis sample pretreatment related projects
(2)Headspace sampler/functional module/unit assembly and related parts and accessories can be: buy, rent or trade-in
