  • Pycnometer Density Measurement Equipment G Denpyc 2900 - China

    price: 1.00 Dollar US$

    G-DenPyc 2900 gas pycnometer true density analyzer introduction A gas pycnometer operates by detecting the pressure change resulting from displacement of gas by a solid object. Expanding a quantity of gas at known pressure into an empty chamber and measuring the pressure establishes a baseline. Then a sample is placed in the chamber and the chamber is resealed. The same quantity of gas at the same pressure is again expanded into the sample chamber, and the pressure is measured. The difference in the two pressure combined with the known volume of the empty sample chamber allows the volume of the sample to be determined by way of the gas law. The accuracy and precision of the gas pycnometer in determining density is good, but the method relies greatly on the cleanliness of the sample material and purity of the analysis gas. In this case, Gold APP Instruments had explored a smart sample preparation degasser for materials handle, can guarantee to gain the "cleanliness" testing data. G-DenPyc 2900 gas pycnometer true density analyzer parameters 1. Analysis Method: Volume displacement method/gas expansion principle
    2. Versatility: true (also terms as real, absolute, apparent or skeletal) density analysis, rigid foam materials’ percentage of open/closed spaces analysis
    3. Experimental Pressure: external vacuum pump is available, can adopt negative pressure (0-1Bar) or positive pressure (1-2Bar) two modes to analysis
    4. Accuracy: accuracy ±0.02%, repeatability ±0.01%, resolution can reach 0.0001 g/cc
    5. Sample Ports: three samples analysis ports
    6. Sample Container: provide 3ml, 10ml, 15ml and 70ml standard containers, also can customize any volume containers from 1-500ml. 7. Pressure Accuracy: imported high-precision pressure transducer, accuracy can reach 0.05% F.S., stability 0.025% F.S.
    8. Adsorbate Gas: high purity Helium or air or Nitrogen
