Brief introduction
Egyptian gold spectrum technology independently developed specific surface area measuring instrument , static volumetric method for measuring principle . Compared to similar domestic products, a number of original technology adoption to make our products more perfect overall performance , accuracy and consistency of test results to further improve the stability of the testing process stronger, reached the international advanced level, some functionality beyond foreign products . Our products are designed more from the perspective of the user point of view, so that V-Sorb 2800S surface area analyzer products have a fully automated operation , user-friendly interface , easy to learn ; joint ventures or through the use of imported spare parts , greatly improving the product reliability and service life. Improvement and strict product manufacturing and testing processes on the overall design of the product , to ensure that products more in line with actual needs of users

Features
1) The original cartridge piping systems integration , the use of imported container line , significantly reducing pipeline connection point , greatly reducing the leakage rate , improve the ultimate vacuum.
2 ) modular design , integrated container line , to be manually connected components less conducive to demand configuration and post extensions according to user needs , is conducive to maintenance and replacement .
3 ) imported from Germany, two-stage vacuum pump , low noise , stable operation , anti-oil back to functional excellence , extreme high vacuum, up 4x10-2Pa (3x10-4Torr).

4) using widely used in industrial control systems , programmable controller solenoid valve control system , anti-jamming capability. Greatly improve the stability of the instrument , installation and removal are very convenient;
5 ) The unique design of the test system and the sample line tubing separation structure effectively prevents the impurities generated in the process of sample contamination on the test pipeline. 

Technical Parameters
Test Method: nitrogen adsorption static volumetric method ;
Host function : adsorption and desorption isotherms measured , BET specific surface area measurements ( single-point and multi-point ), the average particle size is estimated that the true density of the samples was measured , t-plot diagram extrajudicial specific surface area measurements ;
Measuring range : 0.0005 (m2 / g) - to no upper limit (specific surface area ) ;
Accuracy: repeatability error ≤ ± 1.0%;

Vacuum system : V-Sorb original cartridge piping and solenoid valve control system, greatly reducing the tubing dead volume space , small changes to improve the sensitivity of the adsorbed gas detection while reducing the manifold pipe connection point , greatly improving tightness and equipment life;
Level Control : V-Sorb original liquid nitrogen surface control system to ensure full test sample tubes in liquid nitrogen surface relative position remains unchanged , the complete elimination of measurement error due to dead volume changes introduced ;
Measuring modes: "Single nitrogen " and " nitrogen + helium " the perfect combination of two test modes , flexible switching , to meet the needs of the different characteristics of the samples tested ;

Partial pressure range : P / Po accurately controllable range up 5x10-6-0.998;
Ultimate vacuum : 4x10-2Pa (3x10-4Torr);
Vacuum pump : imported double -stage vacuum pump can achieve external and internal placement of two instruments , built instrument can be automatically controlled according to the experimental pump start and stop, thus extending the life of the vacuum pump through software ;
Sample Type : powder , granules , fibers and sheet-like materials ;
Test gas: high purity N2 gas ( 99.999% ) or other ( demand options such as Ar, Kr);
