JINGXIN JB-2020 BET Surface Area Analyzer Dual gas source dynamic test method

Instrument introduction

Solid catalysts in the petrochemical industry, adsorbents for anti-virus filtration, cement, ceramics for building materials and raw materials in the powder metallurgy industry, electrodes for chemical power sources, geological petroleum rock formations, etc. are all solid powder or porous substances. These solids have a large specific surface area and many pores of different sizes and shapes. During use, their physical and chemical processes are carried out on these surfaces and pores. Therefore, testing the parameters of the solid specific surface area is important in production. It is of great significance in scientific research.

The JB-2020 specific surface area Tester refers to the national standard GB/T19587-2017, based on the principle of dynamic low-temperature nitrogen adsorption, using a high- sensitivity sensor and a dual-gas source dynamic test method. Using helium as the carrier gas and nitrogen as the adsorbed gas as the test gas, the solid surfaces of different samples were analyzed. The instrument is calibrated using national standard materials such as GBW (E) 130275. The instrument has reasonable structure, stable performance, high precision, fast testing speed, simple operation, and no special requirements for the Operating Environment. It is suitable for quickly testing the specific surface area of ​​powder materials in various industries, especially the testing of samples with small comparative surfaces.

Application

Specific surface area measurement of porous material powders such as graphite, lithium cobalt oxide, nickel hydroxide, lithium manganate, lithium titanate, lithium carbonate, pharmaceutical powder, catalysts, adsorbents, cement, ceramic raw materials, etc.

Principle

Instrument advantages

1. Proprietary high-precision standard sampler ensures that standard gases of various volumes are stable and accurate.

2. Although there is only one workstation, it is economical and practical, and the test time is short and efficient, each sample takes about 3 minutes.

3. Test method: When the sample tube is placed in the liquid nitrogen cup, the nitrogen in the mixed gas is adsorbed by the sample, the sample tube leaves the liquid nitrogen, and the nitrogen adsorbed by the sample is desorbed. According to the desorption response curve, and then according to the standard volume gas The response curve can calculate the specific surface area of ​​the tested sample.

4. High-sensitivity Detector, low operating temperature, long life, and the Detector will not be damaged due to changes in gas composition.

5. The analysis software can run under the XP/win10 system. The software has complete functions and facilitates comparative analysis of test results. The test results can be displayed, saved or printed. The output test report has functions such as storage, query, comparison, editing, and deletion.
