一、 Introduction:

The APL-TD series 50 bit fully automatic thermal desorption desorption instrument is independently developed and launched by APL Ople. It has a fully automated design, touch screen display, and more convenient operation for automatic thermal desorption. The gas circuit adopts a combination of electric six way valves and solenoid valves, and uses a touch screen for easy editing, saving, and calling of the desorption, injection, and blowback processes of the adsorption tube. It can clearly display the action status of each part during the sample extraction process, and users can easily understand the operation process of the instrument. The heating temperature of adsorption tubes, six way valves, pipelines, etc. can be independently set, and synchronous signals can be output during injection to simultaneously start chromatography and workstations.

二、 Instrument features and main functions:

1. The gas circuit adopts a combination of electric six way valves and solenoid valves to automatically achieve desorption, injection, and blowback cleaning processes;

2. Adopting touch screen for convenient editing, saving, and calling methods;

3. The heating temperature of the adsorption tube, pipeline, and six way valve can be independently set;

4. The machine comes with the function of simulating and sampling standard samples, which makes it more convenient to create working curves through a thermal desorption instrument;

5. Through time programming, automatic functions such as desorption, blowdown adsorption, injection, and blowback cleaning (activation) can be achieved;

6. Using Simple Lock locking sealing technology to achieve simple and reliable fixation and sealing of the sampling tube, efficient work can be achieved by fixing and disassembling the sampling tube in 2 seconds;

7. Adopting semiconductor refrigeration, high cooling efficiency, no need for external refrigeration devices, saving usage costs;

8. Using standard adsorption tubes (89mm long, 6.4mm outer diameter), the adsorption tubes can withstand a temperature of 420 ℃ and are sealed with PTFE caps to ensure longer storage time of the samples;

9. The injection needle is easy to replace and can be connected to all models of GC injection ports at home and abroad.
