Description

The AopuLe fully automatic thermal desorption system is designed for VOCs analysis in air and materials, complying with national standards. It features fully automated tube desorption and injection with zero carryover, and is compatible with GC or GC-MS. Ideal for ambient air monitoring, indoor air quality testing, and material emission tests. Available factory-direct with technical support and customization.

一、 Instrument features and main functions:

1. For the convenience of use, there is no need to use pneumatic methods. The air circuit uses a combination of electric valves and solenoid valves to automatically achieve desorption, injection, and blowback cleaning processes;

2. Using a touch screen for easy editing, saving, and calling of methods, up to 20 methods can be saved;

3. The heating temperature of adsorption tubes, pipelines, valves, etc. 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 leak detection, dry blowing, primary desorption, secondary desorption injection, back blowing cleaning, activation and other functions can be achieved for 100 samples;

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. Adopting international standard adsorption tubes (1/4 inch long about 89mm, outer diameter 3.5 inches about 6.4mm), the adsorption tubes can withstand a maximum 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.

1. Temperature control range of the pipette: room temperature -400 ℃, accuracy: 1 ℃;

2. Temperature control range of valve injection system: room temperature -220 ℃, accuracy: 1 ℃;

3. Temperature control range of sample transfer pipeline: room temperature -260 ℃, accuracy: 1 ℃;

4. One time analysis temperature range: room temperature -400 ℃, accuracy: 1 ℃

5. Secondary analysis temperature range: -35 ℃ -400 ℃, secondary flash evaporation heating rate:>3000 ℃/min;

6. Desorption recovery rate:>98% (depending on the composition);

7. Backblowing cleaning flow rate: 0-100ml/min (continuously adjustable);

8. One time analysis flow rate: 0-100ml/min (continuously adjustable);

9. Number of adsorption tubes: 100

10. The instrument comes with an analog sampling component, with a flow rate of 0-100ml/min; The simulation sampling switch and time setting can be automatically controlled through the host screen program

11. Before analyzing each adsorption tube, perform a tightness check step to ensure that the analysis process of each sample does not leak and to guarantee the accuracy of the data
