- The highest throughput instrument with simultaneous measurement of up to 4 samples.
- New advanced function "GDO (Gas Dosing Optimization)". The best suitable measurement conditions are automatically set using saved customer's adsorption isotherm data.
- An advanced system of direct evacuating and intelligent valve control reduces the measurement time significantly.
- High precision vapor adsorption measurement under the strict temperature control.
- High precision measurement by Advanced Free Space Measurement (AFSMTM)
- LN2 automatic supplier and the dedicated heater enable fully automatic seamless process control from pretreatment to measurement.
- The advanced GCMC method is featured, which enables to perform more precise and higher resolution PSD analysis considering the interaction of actual material surface and adsorbate molecules than the conventional NLDFT (approx. calculation) method.
- The measurement process status and the results can be checked from new remote monitoring function using e-mail system
