【Specific Surface Area・BET Method】Fully Automatic Specific Surface Area Measurement Device Macsorb

Automation and labor-saving of specific surface area measurement. Achieving high reproducibility and high precision through fully automated continuous measurement.

Surface area measurement device based on JIS Z8830. By adopting the BET flow method / single-point method, the measurement time is approximately 10 minutes per sample (excluding pretreatment). With an intuitive user interface, simple, robust, and safe hardware, and a design focused on measurement accuracy and reproducibility, it enables rapid and high-precision surface area measurements. By automating all processes from degassing to adsorption, desorption, and calibration, it prevents human error among operators. The addition of an auto-sampler allows for continuous operation of up to 30 samples, achieving fully unmanned operation day and night. 【Features】 - The device design, which pursues measurement accuracy and reproducibility in the BET flow method / single-point method, minimizes measurement time (multi-point method is optional). - User-friendly, intuitive interface does not require a high level of operator proficiency. - The addition of an auto-sampler enables unmanned operation for 8 to a maximum of 30 samples. - The measurement unit and auto-sampler have a unit structure, allowing for the addition of an auto-sampler after installation. - A wide range of options and accessories, such as external degassing devices (preheaters) and molded product measurement units, are available.

[Measurement Example] Quantifying Lot Differences

Calculated from BET specific surface area and relaxation time! Introducing the differences in wettability of powders with different lots.

We would like to introduce a case study conducted by Majerika Japan Co., Ltd., where six types of powders with different lots were dispersed in distilled water, and relaxation time measurements were performed. The six types of powders were dispersed in water at the same concentration (10 wt%) and subjected to ultrasonic dispersion for 10 minutes, followed by relaxation time measurements. When the relationship between the BET specific surface area and the calculated specific surface area from the relaxation time was graphed, it was represented by two straight lines rather than a single correlation line. This suggests the presence of two types of powders with different chemical properties. 【Case Summary】 ■ Experiment - Six types of powders were dispersed in water at the same concentration (10 wt%). - Ultrasonic dispersion was performed for 10 minutes, followed by relaxation time measurements. ■ Results - The presence of two types of powders with different chemical properties was suggested. *For more details, please refer to the PDF document or feel free to contact us.
