PT-A601 automatic solid-liquid integrated purge and trap instrument
Introduction: PT-A601 automatic solid-liquid integrated purge and trap instrument is a 76-position solid-liquid integrated automatic purge and trap instrument with electronic cold trap. It supports the automatic and accurate sampling of liquid samples into the purge bottle for purging and trapping, and the automatic adding of distilled water to the solid sample for shaking and mixing directly for purging and trapping. Application field: By combining with GC or GC/MS, it can be widely used in environmental analysis, such as the analysis of organic pollutants in drinking water, wastewater, soil, and the analysis of volatiles (such as odor components) in food, etc. . Features: 1 Strong universal performance: can be combined with any brand of gas chromatograph (GC) and (GC-MS) 2 Simple operation, convenient use, full software control, high degree of automation: just put the sample tube into the sample tray, all operations and control are completed by the control software, so the sample repeatability is good; the design of the super large touch LCD panel in the host, Temperature and operation commands can be tracked throughout the process 3 The cold trap adopts semiconductor refrigeration + air cooling, and the low refrigeration temperature can reach -30°C (at room temperature 20°C), which can meet most of the low temperature enrichment requirements 4 The temperature rise of the trap adopts direct resistance heating, and the heating rate is >2400℃/min 5 The built-in foam sensor can detect the foam in the purge tube to prevent the way of contaminating the sample and protect the entire analysis system 6 The user can customize the cleaning times of the sampling needle and purge tube 7 The solid sample bottle can be heated, and can be directly injected into distilled water, oscillated, mixed and purged 8 The trap and the purge tube backflush the gas to separate, reducing cross-contamination between samples. In the back-purge cycle, the compound blown out of the trap will not flow into the purge pipe 9 The water trap removes water vapor at the purge end, which greatly reduces the impact of water vapor on GC and GC/MS 10 The sample pipeline adopts PEEK material and silanized inert treatment stainless steel pipe to reduce pollution residue 11 Hot water can be used to flush pipes and purge pipes to reduce residue 12 All pipelines and six-way valves can be heated by temperature control to eliminate cold spots in the system and reduce sample loss 13 Provides a synchronization interface, which can start the chromatogram and workstation at the same time as the sample is injected Technical parameter: Sample position: 76 positions, 40ml VOA sample bottle Purge tube temperature: room temperature～100℃, step length 1℃ Cold trap (electronic semiconductor refrigeration) temperature control range: -40°C to room temperature, step length 1°C, no need for liquid nitrogen refrigeration Desorption temperature of trap tube: 150～380℃, heating rate>3000℃/min; from 250℃ to 35℃ within 90s Pipeline heating temperature: room temperature～220℃, step length 1℃ Heating temperature of dewatering device: room temperature～400℃ Cleaning distilled water temperature: room temperature～90℃, step length 1℃ Heating of solid sample bottle: room temperature～100℃, step length 1℃ Mixing of solid samples: 5ml of distilled water, shaking and mixing Glass purge tube: 5ml purge tube Trap size: stainless steel material Φ3mm×180mm×0.1mm Purge flow: 10～150ml/min Timing range: 1s～100min Timing error: <0.1% Air pressure resistance: >0.4MPa Synchronization signal output: 2 switching values, the linkage switching time is 1 to 2 seconds Power supply: AC220V 50Hz High power: 800W Instrument size: 640mm*750mm*510mm Instrument weight: about 42Kg
