1 Atmospheric pre concentration host Three stage refrigeration rapid heating system: a semiconductor electronic integrated cold trap that can effectively remove the interference of CO2, O2, H2O, etc. in the air without losing the specified polar compounds in the method, with a capture temperature of~40 ° C. The cold trap can be equipped with up to 3 low-temperature and 3 rapid heating devices to achieve low-temperature water removal, remove CO2, O2, and H2O from the adsorbed air, capture compounds between C2-C16 in the air, and enter the gas chromatography GC or gas chromatography-mass spectrometry GCMS for analysis through valve switching. After injection, it switches to the back blowing high-temperature cleaning mode to maintain a low background of the atmospheric pre concentration system. Three rapid heating control ranges within the capture trap: room temperature -400 ° C, set in increments of 1 ° C (heating rate) at 3000 ° C/min. Built in high-definition 7-inch touch screen control, user-friendly graphical operation interface, easy to learn and use. It can be operated independently and can be used in combination with any brand of gas chromatography or GC-MS. The online recording function of each sample testing parameter can record the actual desorption process parameters of each sample tube, making it convenient for users to understand the analysis process of the sample and better control the optimization and traceability of experimental conditions. |

2 Su code can automatic sampler One or two 12 bit 1-6L Su code tank automatic samplers can be configured. Multiple injection function: The same Su code control can achieve up to 9 repeated concentrated injections, effectively improving parallel detection capability. Equipped with channel reverse cleaning function, it can eliminate residual pollution from the previous cycle. Multiple switching valves and transmission pipelines have heating functions, eliminating sample retention. |

Dynamic Dilution DeviceProduct Features | Product Features
All sample pipelines and fittings are made of inert stainless steel or FEP material.
Standard gas flow control pressure difference and gas resistance calculation calibration, using high inert components throughout the process to meet the preparation of H2S and other sulfides and corrosive gases (DDK-3S type).
Zero gas (dilution gas) flow control stainless steel digital mass flowmeter, flow range 0-2L/min, accuracy+/-1%.
Controlled by system software, the built-in solenoid valve switches between sampling, zero gas, and standard gas pipelines.
Connected to the chromatography system through an internal network port, controlled by PC software, it can perform up to 20 points of automatic calibration or testing to meet the detection needs of different quality control samples.
Through the touch screen on the front panel, users can directly control the built-in 8 dilution ratios or dynamically change the dilution ratios.
