Specific surface analyzer

The specific surface area, also known as the specific surface area, refers to the surface area of ​​1g of solid material, which includes the sum of the internal surface area and the external surface area, commonly denoted by the symbol SA, and the unit is m2g-1, which is the most important physicochemical parameter to characterize the solid property. one. Therefore, the specific surface area analyzer is an indispensable instrument for production, scientific research and teaching.

Scope of application

Specific surface area measurement chromatography is widely used in nano materials, catalysts, cleaning agents, adsorbents, filter aids, column packing, activated carbon, alumina, diatomaceous earth, sepiolite, silica gel, rare earth, coal, ceramics, graphite, The analysis and determination of various products such as batteries and cements have been widely used in the research and development, production control, product application, and physical property testing of various solid powder new materials.

main feature

The use of head-up chromatography to determine the specific surface, the test speed; correction of blank values, eliminate system errors, high measurement accuracy; "Gaussian curve a little" quantitative, quantitative fast and accurate.

Instrument performance

Measurement range: The specific surface area of ​​the sample can be measured regardless of size Measurement accuracy: The average deviation ≤ ± 2%

Test speed: General sample ≤ 5min

Sensitivity: S≧10000Mv.ml/mg

Quantitative methods

Based on the BET principle, the chromatogram elution curve is based on the Gaussian agenda, and is quickly and accurately quantified according to the “Gaussian curve method”.
