Pressure Composition Isotherm Data Measure System

1.Analysis Method: static volumetric principle, high pressure gas sorption principle
2.Versatility: adsorption/desorption isotherms measurement (atmospheric to 500a ), Gibbs supercritical adsorption measurement
3.Data Reduction: Langmuir model regression isotherm, PCT(Pressure-Composition-Temperature) or PCI (Pressure-Composition-Isotherm) diagram/curve/isotherm measurement, Langmuir maximum adsorption constant L and adsorption pressure constant B measurement; Langmuir correction model loading-ratio correlation regression (LCR) isotherm; Ono-Kondo (OK) lattice model isotherm regression; adsorptive gas density and vapor-liquid equilibrium accuracy calculation under different pressures and temperatures
4.Measuring Ranges: continuous adsorption and desorption measurement from atmospheric to 200Bar pressure
5.Accuracy: repeatability errors <3%
6.Temperature Range: cryogenic to 500a , accuracyA 0.1a
7.Sample Ports: two samples analyzing and two degassing, stainless-steel micro welding sample cells, software integrated temperature PID adjustment
8.Transducer Accuracy: imported high precision transmitter, accuracy can reach 0.05% of F.S. (full-scale), long-duration usage stability is 0.025% of F.S.
9.Ultimate Vacuum: 4x10-2 Pa (3x10-4 Torr), molecular pump system (1x10-6 Pa) is optional
10.Adsorbate Gas: high purity nitrogen, CO2 or others (Ar, Kr, H2, CH4 etc.)
11.Data Acquisition: high-precision and high integration data acquisition modules, minimal error.
