ATDS-3400SType dual channelThermal Desorptioninstrument

1、 Instrument Introduction

ATDS-3400SType dual channelThermal DesorptioninstrumentIt's oneNew modelSample pretreatment deviceThis instrument integrates two thermal desorption instruments and can be used by two gas chromatographs simultaneously, which is economical and practical.

2、 InstrumentPurpose and application scope

ATDS-3400S-shaped dual channelThermal desorption apparatusCan be used with all imported and domestic gas chromatographs, and the minimum detection concentration of volatile organic compounds in the environment can reachPpb level. ATDS-3400S-shaped dual channelThermal DesorptioninstrumentExcept for meetingGB50325-2020Indoor Environmental Pollution Control in Civil Construction Engineeringstandard”Benzene in Indoor Air、Toluene, xyleneDetermination of”In addition to the determination of total volatile organic compounds (TVOC) in indoor air, it can also be applied to the following fields:

1. Occupational safety, industrial hygiene, and environmental monitoring;

2. Rapid identification of unknown atmosphere;

3. Analysis of spices and essence;

4. Assessment of toxic substance accidents (when personnel can safely return to the accident site);

5. Security monitoring of the perimeter environment of chemical weapons warehouses;

6. Quality control testing in the polymer and packaging industries;

7. Sampling and determination of volatile organic compounds and aldehydes and ketones in vehicles；

8. Residual analysis of drugs and court samples;

9. Collecting exhaled gases from patients and detecting volatile drug metabolites in their blood in hospitals.

3、 InstrumentCharacteristics and main functions

1. Integrated design of dual channel thermal desorption instrument and analog sampling, more practical and convenient;

2. Automated design,One machine with multiple uses,Easy to operate;

3. minuteMachine control,large screenlcd,touchKeyboard, numeric input, main functions include:

⑴ Method parameter settings, real-time working status, and running time;

⑵ separateabsorbFurnace, injectionvalveAnd the sample transfer tube,threeLu JunindependenceHeating and temperature control;

⑶ settingProgram control,Press the run button to automatically complete the entire sample analysis；

⑷ approvestorage9 convenient methodsCall at any time, achieving fast startup and analysis;

⑸ Can start synchronouslyGC、 The chromatographic data processing workstation can also be started with external programs;

4. Equipped with an external carrier gas regulation system, there is no need forThe GC instrument can be operated with any modifications or changes, canUse the original instrument carrier gas;

5. Two way thermal desorption apparatusCan simultaneously perform desorption, injection, and blowback processes；

6. 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;

7. Through foreign affairs time programming, automatic functions such as desorption, injection, analysis, and post analysis blowback can be achieved;

8. For active substance analysis, an elastic quartz tube can be selected as the sample transfer tube;

9. driveofThe key components use imported pneumatic components;

10.The injection needle is easy to replace and can be connected to all models at home and abroadGCInjection port;

11.In order to complement importsGC is more convenient and accurate to use, and this instrument is also equipped with dedicated interfaces for various imported instruments, making it easy to connect.
