Brief introduction JW-DX type dynamic adsorption ratio surface analyzer, JW invention patents, innovative structure, each sample separate adsorption, mutual non interference, adsorption peak sharp, sensitivity greatly improved, through the adsorption peak direct contrast to surface, test accuracy, stability, lower than the lower surface of a number of grade, very suitable for battery positive and negative electrode materials, especially graphite and other small than surface materials testing. Application domain (recommended) battery materials: lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate, graphite, three yuan of materials such as cathode materials; The pharmaceutical excipients and other surface materials; Technical parameter 1 dynamic than surface determination, JW invention patent (Patent No. 201410320453.2), the use of adsorption peak, the test process is simplified, completely avoid the sample desorption is not completely possible error;The 2 instrument is equipped with 4 independent analysis can be performed at the same time, 4 samples of surface area determination, measurement range 0.01m2/g-500 m2/g, especially for the testing of small surface samples 3. Each sample independent adsorption, realizes the multi sample without interference and to test for differences, and fully guarantee the parallelism of four sample testing results; test repeatability is less than or equal to ≤± 1.0%; 4 each sample gas path is directly connected with the thermal conductivity detector, and is not diluted by other gas paths, and the absorption peak is sharp and the sensitivity is greatly improved; 5. Instrument internal pipeline connection adopts the fast insertion connectors to connect, convenient, fast, durable, non leakage, fully meet the atmospheric dynamic chromatographic compare table test area, humanized design; 6 the stability of the test results can greatly reduce the measurement error by using the thermal conductivity detector constant temperature system; 7 independent research and development of automatic data acquisition and processing software, advanced and simple, easy to operate, with a pioneering, the times! 8 instrument specification: long 610mm x width 360mm x high 690mm, weight about 30Kg; 9 use the power requirement: AC 220V ± 20V, 50/60HZ, the maximum power 300W; Optional degassing machine parameters: 1 gas station: 4 station; 2 degassing temperature: room temperature to 400℃±1℃; 3 vacuum pump limit vacuum: 100Pa; 4 specifications: length 400mm x width 300mm x high 550mm, weight about 10 Kg; 5 use the power requirement: AC 220V ± 20V, 50/60HZ, the maximum power 300W;
