Measurement of specific surface area of powdered zeolite by the BET method.

Supports measurement of catalysts and activated carbon! Analysis of pore distribution is also possible.

We conduct specific surface area measurements of powdered zeolite using the BET method. The BET theory is known as a model and mathematical formulation of the physical adsorption phenomenon of gas molecules on solid surfaces, allowing for the calculation of the specific surface area of powders by measuring the amount of gas molecules physically adsorbed on the surface of powdered solids. In the BET plot of synthetic zeolite, parameters are calculated in the relative pressure range of 0 to 0.05, resulting in a specific surface area of 938 m²/g. [Other Applications] - In addition to zeolite, it can also be used for measuring the specific surface area of catalysts and activated carbon. - It is also possible to analyze pore distribution. *For more details, please download the PDF or feel free to contact us.

Determine particle size and particle size distribution! Example of measuring the particle size of silica and alumina particles in an aqueous medium.

Dynamic light scattering allows for the measurement of particle size and size distribution of nanoparticles dispersed in a liquid without separating the particles. Here, we present an example of measuring the particle size of silica and alumina particles in an aqueous medium. Particles in a solution exhibit Brownian motion that depends on their size, and the fluctuations in the scattered light produced when the particles are illuminated depend on their size as well. By observing and analyzing these fluctuations, we can determine the particle size and size distribution. [Alumina Measurement Results and Discussion] - As alumina approaches neutrality from strong alkaline conditions, it nears its isoelectric point. - The surface charge of the particles decreases. - The repulsion between particles diminishes. - It can be inferred that particle aggregation is occurring. *For more details, please refer to the PDF document or feel free to contact us.*

Important analysis items for performance evaluation and quality control of functional materials! Evaluation of pore size and pore distribution of non-woven sheets and membrane materials.

This is an example of evaluating the maximum pore diameter and pore size distribution of non-woven fabric sheets using the bubble point method. The sample is immersed in a chemical solution and air pressure is applied. The pressure is increased until it overcomes the surface tension of the chemical solution absorbed in the sheet, resulting in the appearance of bubbles; this pressure is referred to as the bubble point. The maximum pore diameter can be calculated based on the bubble point pressure and the surface tension of the chemical solution. 【Calculation Formula】 ■d = Cy/P ・d: Maximum pore diameter ・C: Constant ・y: Surface tension of the chemical solution ・P: Differential pressure *For more details, please refer to the PDF document or feel free to contact us.

Introducing examples of measurement cases for important management items in the production of lithium-ion batteries and all-solid-state batteries!

We would like to introduce a case of particle size measurement of cathode active materials using laser diffraction conducted by our company. In air or liquid, laser light is irradiated onto particles, and the angular dependence of the intensity of light scattered by the particles is measured. The angular dependence of the scattered light intensity is measured, and from that data, the particle size distribution (particle size distribution) is calculated. Commercially available reagents were used as samples, and measurements were conducted in a dry state without dispersing in a solvent. The particle size measurement results for NMC oxide showed a monodisperse state with particle sizes below several tens of micrometers, and the median diameter was calculated to be 12 μm. 【Case Overview】 ■ Measurement Method ・Dry ■ Particle Size Measurement Results for NMC Oxide ・Monodisperse state with particle sizes below several tens of micrometers ・Median diameter is 12 μm *For more details, please refer to the PDF document or feel free to contact us.

Parking space management refers to the real-time display of parking availability and the management of efficient use of parking spaces. By utilizing Hotron's sensors, drivers can quickly discover available parking spaces, enabling efficient parking lot operations. For large parking lots, we recommend the "Floor Management Method" and "Block Management Method," which focus on cost reduction. Sensors are installed at regular intervals to count and manage the number of passing vehicles. This method offers the advantages of easy installation and low costs. 【Target Products】 - Vehicle Count Sensor CCS2 - Ultrasonic Sensor HM-UX2/UW2 For smaller facilities, we recommend the "Parking Space Management Method," where sensors are installed in each parking space to display availability with high accuracy. By providing reliable occupancy information, this method helps reduce unnecessary entry of new vehicles and ensures safe parking lot operations. 【Target Products】 - Occupancy Detection Sensor HM-UX2/UW2 - Occupancy/Pass Detection Sensor HM-LC6 - Occupancy Detection Sensor HM-LC7/LC7-FLS - Occupancy/Pass Detection Sensor HM-S6 - Occupancy Detection Sensor HM-S8
