Instrument performance Test principle : JB-1 type specific surface area analyzer using dynamic nitrogen adsorption method using gas chromatography , low-temperature adsorption principle , the use of highly sensitive sensors, double gas source dynamic testing method with helium as the carrier gas, nitrogen gas is adsorbed gas as test gas , solid surface for different samples were analyzed . Measuring range : 0.1m ² / g ~ 3500m ² / g Test accuracy: measurement error ≤ ± 1% ( national standard ) Test time: one sample per measurement takes 30 minutes each time to test two samples . Analysis Software : In Windows XP system running , powerful software . Test method: When the sample tube immersed in liquid nitrogen , the nitrogen gas mixture adsorbed by the sample , then the sample tube leaving liquid nitrogen adsorbed by the sample desorbed nitrogen , adsorption and desorption based on the response curve can be calculated by specific surface area of the sample measured . Power supply : AC220V ± 10% 50Hz 300W Host Shape: Long 700mm width 300mm height 600mm Instrument features: 1 test of national patent technology , proofreading using the national standard material.
