PT-75D fully automatic blowing and trapping device Introduction: The APL-PTC series automatic purge and capture container is mainly used for VOC analysis of volatile organic compounds in water and soil, as well as for the analysis of volatile compounds in food. The compliance standards include: HJ605-2011 Determination of Volatile Organic Compounds in Soil and Sediments by Purge Trap/Gas Chromatography-Mass Spectrometry HJ639-2012 Water quality - Determination of volatile organic compounds - Purge trap/gas chromatography-mass spectrometry method HJ686-2014 Water Quality - Determination of Volatile Organic Compounds - Purge Trap/Gas Chromatography Method Features: 1. Convenient operation, method parameter setting, real-time animated display of working status, fully automatic operation of 1-75 samples; 2. The injection valve, sample transfer tube, water trap, and capture tube desorption zone are all individually heated and temperature controlled; 3. Set up the analysis program, press the run button to automatically complete sample purging and injection, and start chromatographic analysis; 4. Automatically achieve functions such as blowing, trapping, desorption, injection, and back blowing cleaning through time programming; 5. Equipped with magnetic stirring function, the sample can be automatically stirred, and the stirring speed can be adjusted; 6. The sample transfer tube and injection valve have automatic backflushing function to avoid cross contamination of different samples; 7. It can automatically start the dedicated startup line interface for various brands of GC and GCMS, and can connect all models of GC and GCMS at home and abroad; 8. The sample is removed from the water trap to prevent water vapor from entering the capture tube and reduce the impact of water vapor on GC and GCMS; Technical parameters: Temperature control range of the water trap: room temperature -240 ℃, set in increments of 1 ℃, with a heating power of about 400W; The temperature control range of the valve injection system: room temperature -220 ℃, set in increments of 1 ℃, with a heating power of approximately 60W; The temperature control range of the sample transmission pipeline: room temperature -220 ℃, set in increments of 1 ℃, with a heating power of approximately 40W; The capture tube adopts electronic refrigeration, and the adsorption and desorption temperature control range is -30 ℃ to 400 ℃, with any increase of 1 ℃; Sample temperature control range: room temperature -240 ℃, set in increments of 1 ℃, heating power of approximately 200W; Sample bottle specification: 40ml; Purge flow rate: 0-100ml/min (continuously adjustable); Blowback flow rate: 0-100ml/min (continuously adjustable);
