Thermal desorption
For:
Consultation Contact usATDS-20A MAX automatic thermal desorption instrument
1、It has functions such as power on self check, fault alarm and prompt, temperature overload protection, leakage protection, and gas circuit pressure difference alarm
2、The gas path control adopts switching valves and solenoid valves, with stable performance and avoiding sample contamination
3、All gas pipelines have undergone passivation treatment
4、Low temperature secondary desorption utilizes electronic refrigeration and second-order thermal desorption processes, resulting in narrow chromatographic peaks
5、The sample transfer tube and injection valve have automatic backflushing function to avoid cross contamination of different samples
6、7-inch capacitive touch screen control, using electronic pressure sensors, real-time display of pressure status
7、Independent air duct to improve the refrigeration efficiency of the cold trap
8、Modular design, with 5 major modules that can be grouped and independently maintained and upgraded
9、This machine comes with a standard sample simulation sampling function, which can be used to create working curves through a thermal desorption instrument
10、Fully automatic low-temperature secondary desorption, using semiconductor refrigeration needle holding device to assist vertical operation and save consumables
