DX400 specific surface area analyzer Introduction: DX400 is our company's latest high-efficiency specific surface area analyzer, which is based on the principle of dynamic chromatographic analysis to achieve rapid determination of BET specific surface area. Compared with traditional products, it achieves two major advantages: accuracy and speed Accurate: It can accurately test standard samples with an ultra small specific surface area of 0.1 m2/g, accurate to 0.01 m2/g. Fast: The testing speed is three times faster than traditional products, and can achieve ultra-high testing efficiency of 28 standard samples in one hour. Very suitable for testing positive and negative electrode materials of batteries such as lithium cobalt oxide, ternary materials, lithium iron phosphate, graphite, silicon carbon, and other small specific surface area samples. characteristic: 1. Accurate calculation of desorption peak The peak area calculation is based on the desorption process during the adsorption desorption process. After experimental verification, this method has higher accuracy and stability than the adsorption method, and is very suitable for the determination of small specific surface areas of battery positive and negative electrode materials such as ternary materials and graphite; The experimental method can be either single point BET or multi-point BET. 2. Can be integrated and remotely accessed The instrument communication interface is a LAN port, which can realize centralized control of one computer as the upper computer, and can remotely access and control the upper computer. 3. Independent degassing system Equipped with a completely independent degassing system as standard, with two options of blowing and vacuum, the sample pretreatment is more intelligent, flexible, and convenient. Not occupying the analysis station for pre-processing samples, improving testing efficiency. 4. Visual display of operating status The front panel of the instrument is equipped with a status display system, which displays the working principle diagram of the instrument. LED lights are added to each valve position to indicate the on/off status of the solenoid valve, allowing for intuitive judgment of the instrument's operation during the experiment. 5. Sample card head patented technology It retains the simplicity and ease of operation when installing sample tubes with quick connectors, while avoiding air leakage caused by damage to the sealing components due to repeated use of quick connectors. The card head can be disassembled and reassembled repeatedly while ensuring sealing, and can withstand higher pressure without leakage compared to quick connectors. 6. Security protection mechanism To ensure the safe operation of the instrument, (1) a wake sensor is added to the TCD detector to prevent dry burning, ensure the stability of the TCD signal, and extend the service life of the TCD detector. (2) Develop a low-level monitoring program to monitor the operation status of the instrument, automatically control the instrument when there are abnormalities or other dangers, relieve the abnormal conditions that cause danger, and protect the safety of the instrument and operators. 7. Multiple Dewar flasks to choose from High performance vacuum glass inner dewar bottle, customized and produced using self-developed technology, with both the insulation effect of glass inner liner and the safety performance of metal inner liner, not fragile; High cost-effective vacuum glass inner Dewar flask with good insulation effect, capable of continuously testing more than 10 samples; Metal lined Dewar flask, capable of obtaining accurate results with extremely high safety factor; Technical parameters: Test principle: Flow chromatography low-temperature nitrogen adsorption Test gas: high-purity 3:7 nitrogen helium mixture (99.9999%) Detector: A customized thermal conductivity cell with an accuracy of 0.1mV, capable of testing samples with an accuracy of 0.1 m2/g up to 0.01 m2/g. Specific surface area range:>0.1 m2/g, repeatability of standard sample testing<1%, parallelism<1%, long-term stability<1% Analysis stations: 4 Host specifications: length 700mm x width 410mm x height 785mm, weight approximately 30 Kg Environmental temperature requirement: 15-35 ℃ Environmental humidity requirement: 20% -80%, non condensing environmental humidity Power requirements: 100-240VAC, 50/60HZ, maximum power 200W Recommended application areas: lithium iron phosphate, ternary, graphite, lithium cobalt oxide, lithium manganese oxide and other battery positive and negative electrode materials, as well as other small specific surface area materials.
