    Namesurface area analyze

    ModelJW-DA

    Introduction

     

    Analysis method

    Dynamic method, Langmuir surface area analysis, Direct comparison, BET (single-point, multi-point ), the average particle size estimating the outer surface area of carbon black

    Technical parameters

    Measuring range: 0.01 (m / g) - to no upper limit (surface area)
    Test Accuracy: 1% repeatability error
    Sample types: powder, particles, fibers and sheet materials, widely
    Sample No: analysis four samples simultaneously
    Gas: carrier gas,high purity He (99.99%), adsorbed gases, high purity N2 (99.99%) or other (such as Ar, Kr)
    Time: direct comparison method, per sample 3min; 5-point BET, per sample 15min; results are automatically obtained by the real-time software.
    Pressure: atmospheric pressure, conducive to rapid surface area analysis.
    Data collection: high-precision two-way digital acquisition module, the most flexibility to complete the most comprehensive data collection, the error is small, anti-interference ability will help improve the accuracy of the results of surface area
    Data process: standard window interface, easy to understand, learn, operate, rich analysis model, high image resolution, easy to maintain, taking system post-upgrating into account.
    Quality Certificate: CE, China Metrology Institute Certificate, Test Report of China Science and Technology, New Instrument Certification, GB / T 19001-2008 Quality Management System Certificate
