SSA-3620Fast Specific Surface Area Analyzer

Overview:The SSA-3620 specific surface area analyzer is a further superior to the SSA-3600 and has undergone nearly 20 years of market testing. This device complies with the national standard GB/T19587 and uses the dynamic chromatographic reference method proposed by Nelsen and Eggertsen as the measurement method. In a low-temperature liquid nitrogen environment, a helium nitrogen mixture is continuously introduced into the sample tube, and the nitrogen in the mixture begins to be adsorbed by the sample until saturation, which is manifested as a downward peak in the software; Then the Dewar flask was lowered, and during the temperature rise (-196 ℃~room temperature), the nitrogen in the sample began to desorb until it was completely removed, showing an upward positive peak in the software.
