[New Feature] Evaluation of specific surface area and pore distribution without the need for helium gas.

Developed and released a new feature that enables the evaluation of specific surface area and pore distribution without using helium gas!

At MicrotracMRB, we have developed a new feature called the 'AFSM2' free space continuous measurement method, which does not require helium gas due to the recent shortage of helium gas supply. By using an adsorbate such as N2 in advance to determine the "free space value of the blank sample tube" (calibration), we calculate the adsorption amount by subtracting the "excluded volume of the sample determined from the sample mass and density" from the free space (calculated value). The difference in free space due to the liquid nitrogen level during pre-calibration and adsorption measurement is automatically determined using a reference tube, so there is no need to keep the liquid level constant. 【Features】 ■ Continuous measurement of free space: Possible ■ He gas: Not required ■ Free space (initial value): Pre-measurement + reference tube correction ■ Sample tube ID management: Required (register ID and volume in software) ■ Measurement time: Approximately 45 minutes shorter ■ Direct measurement of net adsorption amount: Possible *For more details, please refer to the PDF document or feel free to contact us.
