Introduction: ATDS-20A type full automatic thermal desorption instrument is our company independently developed a full automatic design, touch large screen display, operation is more convenient, continuous operation of 20 samples of a new generation of full automatic thermal desorption instrument. Can also be based on user needs to increase the room temperature two desorption parts or low temperature two desorption parts. ATDS-20A full automatic thermal desorption instrument can be equipped with all the chromatograph with imported and domestic gas. Features: 1. Can be automatically run up to 20 samples, no need staff; 2. Boot self-checking, fault alarm and tips to automatically locate the sample plate; 3. Equipped with external load air conditioning system without any modification and changes, the GC instrument can sample analysis, also can choose the original instrument carrier gas; 4. Through time programming, automatic desorption, purging adsorption, desorption, sampling again, back washing, etc; 5. Electronic refrigeration and second-order thermal stripping process in place to ensure that get narrow chromatographic peak shape; 6. Sample transfer line and into the valve have auto reverse function, avoid the cross contamination of different samples; 7. In order to form a complete set of imported gas chromatograph to use more convenient and accurate, the instrument is equipped with a special pick up against various kinds of imported equipment Technical parameters: 1. The desorption temperature control range: 1 at room temperature to 400 ℃ with increment 1 ℃ set; 2. The temperature control valve filling system: at room temperature to 220 ℃ with increment 1 ℃ set; 3. The sample range of transmission line temperature control: at room temperature to 260 ℃ with increment 1 ℃ set 4. Desorption temperature control range: 2 at room temperature to 400 ℃ with increment 1 ℃ set; (heating rate > 2000 ℃ / min) 5. Cold trap temperature control range: - 30 ℃, 50 ℃ incrementally 1 ℃ was set (using the most advanced electronic refrigeration devices, without liquid nitrogen refrigeration) 6. The temperature control precision: < plus or minus 0.1 ℃; 7. Gradient temperature control: "plus or minus 0.1 ℃ 8. Sample position: 20 9. The recovery rate of desorption: > 98% (and components); 10. The counter blowing clean traffic: 0 ~ 600 ml/min (adjustable); 11. Simulation sampling flow: 100 ml/min. 12. Instrument size: 450 * 360 * 360 mm3; 13. The instrument weight: about 30 kg.
