Surface DX400

Outline

The Altamira DX 400 is the latest surface area analyzer based on the principle of dynamic chromatographic analysis. It achieves rapid determination of BET specific surface area, surpassing traditional products in terms of both accuracy and speed. Accuracy: It can accurately test standard samples with ultra-small specific surface area of 0.1 m2/g, with an accuracy of 0.01 m2/g. Speed: The testing speed is 3 times faster than traditional products, achieving ultra-high testing efficiency of 28 samples in 1 hour. Suitable for testing the positive and negative electrode materials of lithium cobalt oxide, ternary materials, lithium iron phosphate, graphite, silicon carbide and other small specific surface area samples.

Distinctive

  • The unique Dtech technology integrates Dstable stable testing technology, Dcal automatic calibration technology, Dtrap precise testing technology, Dsignal efficient testing technology, and Dctrl anti-blowing control technology, contributed to the high testing efficiency of the DX 400 series. The repeatability, stability, accuracy, and parallelism of the test results all reach the industry-leading level, especially for samples with a specific surface area less than 1 m2/g.
  • Dstable stable testing technology
  • The unique Dstable stable testing technology is adopted to ensure that the TCD signal is not affected by the liquid nitrogen level changes during the instrument testing process, ensuring the repeatability of the test results.
  • Dctrl anti-blowing control technology
  • The exclusive Dctrl Anti-blowing control technology is used to prevent instrument airway pollution caused by samples being blown away during testing, protect the safe operation of the instrument, and prolong the instrument's lifespan.
  • Dcal automatic calibration technology
  • The Dcal automatic calibration technology is adopted to ensure that the aging of the TCD filament during the instrument's lifecycle does not affect the test results, thus ensuring the stability of the test results throughout the instrument's lifecycle.
  • Dsignal efficient testing technology
  • The unique Dsignal efficient testing technology is adopted to achieve efficient completion of single-point BET test results within 7 minutes, and the testing efficiency can reach up to 4 samples tested in 7 minutes.
  • Dtrap precise testing technology
  • Dtrap precise testing technology The unique Dtrap precise testing technology is adopted to ensure that the control accuracy of the TCD signal during the testing process reaches 0.1mV, and is not affected by the environment, thus ensuring the accuracy of the test results.
