Chromatography, also known as head-front chromatography (frontal chromatography), refers to continuously pass into the gas (or liquid gas) samples, and sample composition and sample are kept constant. Carrier gas after the sample into the column sub-samples or dissolved in the weak adsorption of the first component to the pure state out, followed by the outflows and the second is the weakest component of the mixture of weak and the weakest, second weak and the third a mixture of three components and weak, and so on. , Specific surface area measured by gas chromatography, surface area analyzer Shanxi Province / Inner Mongolia / Beijing, determination of specific surface area of gas chromatography, surface area analyzer, 


 This method can be used to trace impurities from a mixture containing a pure component in the cut, while not suitable for wide separation of the mixture components; but it is suitable for head-chromatography determination of specific surface area and pore size of solid materials and other physical parameters. Surface area analyzer Shanxi / Inner Mongolia / Beijing 
 May take a full day, if the testing process does not achieve a fully automated, all the time that testers can not leave, and to a high degree of concentration, observation instrument panel, control knobs, too easy to be led to the failure of the testing process, which testers will waste a lot of valuable time. 

 Surface area analyzer, specific surface area analyzer, specific surface area of gas chromatography, analysis of specific surface area of gas chromatography 

 Surface area, also known as surface area, means the substance has 1g of solid surface area, which includes the internal and external surface area and, commonly used symbols to represent SA in units of m2g-1, which is characterized by the solid performance of the most important physical and chemical parameters one. Thus, the specific surface area analyzer is the production, research and teaching equipment indispensable. 
 Detector surface area, surface area detector, detection of specific surface area of gas chromatography, surface area-specific gas chromatography detection
