ATDS-3400B/3400B-II 

Automatic low-temperature (dual channel) secondary thermal desorption device (single tube/double tube)

Product Features

1、Equipped with power on self test, fault alarm and prompt

2、Color touch screen, controlled by microcomputer program, capable of setting method parameters, displaying working status and running time in real-time

3、Desorption zone, injection valve, sample transfer tube, and secondary desorption zone, all four channels are individually heated and temperature controlled

4、Set up the analysis program and press the run button to automatically complete the entire sample analysis

5、Can add room temperature secondary desorption components or low temperature secondary desorption components according to user needs

6、The use of electronic refrigeration and second-order thermal desorption processes helps to obtain narrow Serno peaks in experimental results

7、Equipped with a dedicated interface that can synchronously start various GC, GCMS, and chromatographic data processing workstations both domestically and internationally

8、Through time programming, automatic functions such as desorption, blowing adsorption, re desorption, injection, and back blowing cleaning are achieved

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、The sample transfer tube and injection valve have automatic backflushing function to avoid cross contamination of different samples

11、For active substance analysis, elastic quartz tubes can be selected as sample transfer tubes
