Introduction: ATDS-3600A automatic thermal desorption apparatus can be applied to the "HJ-644-2013 Ambient Air Volatile Organic Compounds Determination of the absorption tube sampling - thermal desorption gas chromatography - mass spectrometry", "HJ / T 400-2007 Vehicle Volatility Organic matter and aldehydes and ketones sampling method "," GB / T18883-2002 indoor air quality standards "," HJ583-2010 solid adsorption / thermal desorption - gas chromatography "," GB 50325-2010 civil engineering indoor environmental pollution control Standard "and other standards. Features: 1. Can run up to 20 samples automatically, without personnel watch; 2. POST, fault alarm and prompts, automatic positioning sample tray; 3. Microcomputer control, the main functions are:
⑴ method parameters set, real-time animation shows the working status, running time;
⑵ sample area, injection valve and sample transfer tube, three are individually heating temperature control;
⑶ set the analysis program, press the run key to complete the entire sample analysis;
⑷ with a variety of extensions: According to user needs to increase secondary desorption components at room temperature or low temperature secondary desorption components, purge and trap, cold traps;
⑸ GC can be started simultaneously, chromatography data processing workstations, foreign programs can also be used to start the device; 4. With an external carrier gas regulation system, without any modifications and changes to the GC instrument, you can carry out injection analysis, can also choose the original instrument carrier gas; 5. By time programming, automatic desorption, injection, cleaning and other functions; 6. Sample transfer tube and injection valve with automatic backflush function, to avoid cross-contamination of different samples; 7. In order to support imported gas chromatograph to use more convenient and accurate, the instrument is also equipped with a dedicated interface for a variety of imported instruments, easy to connect; 8. For the active material analysis can be optional flexible quartz tube as a sample delivery tube; 9. Injection needle replacement convenient, can be connected to all models of GC injection at home and abroad. Technical Parameters: 1. Sample zone temperature control range: Room temperature -400 ℃ in increments of 1 ℃ set heating power of about 200W; 2. Valve injection system temperature control range: Room temperature -220 ℃ in increments of 1 ℃ set heating power of about 60W; 3. Sample transfer line temperature control range: Room temperature -220 ℃ in increments of 1 ℃ set the heating power of about 40W (For operational safety, the transmission line temperature control using low-voltage power supply); 4. Temperature control accuracy: <± 0.5 ℃; Temperature control gradient: <± 0.5 ℃; 6. Sample position: 20 bits 7. Desorption recovery:> 95% (and components); Backflush cleaning flow: 0 ~ 400ml / min (continuously adjustable); 9. Instrument size: 450 × 360 × 510mm3; Instrument weight: about 25kg.
