g-denpyc 2900 true density analyzer parameters
analysis method: volume displacement method, gas expansion method
experimental pressure: external vacuum pump is available, can adopt negative pressure (0-1bar) or positive pressure (1-2bar) two modes to analysis
sample ports: three samples analysis simultaneously
pressure accuracy: imported high-precision pressure transducer, accuracy can reach 0.04% f.s., stability 0.025% f.s.
Adsorbate gas: high purity he or n2 (99.999%)
g-denpyc 2900 true density analyzer features
data reduction: high-precision gas density calculation model eliminates measurement errors caused by non-ideality gas state, can increase analysis accuracy
thermostatic system: analysis modules designed with thermostatic system can control temperature up and down easily, also hold modules stay at the best temperature(25 c) which can restrain transducer temperature drift and keep system temperature uniformity; system can maintain temperature at a fixed value for some fixed-temperature-required samples
control system: programmable logic controller (plc) system obtains high integration and strong anti-interference, software operated fully automated analysis enables freely choose of multi experiment modes
analysis management: programmable built-in system, touch screen, usb type external keyboard and mouse, operated by connecting to computer is available
manifolds system: patented v-sorb assembling-installed manifolds system can improve sealing performance and reduce dead space largely, enhance system temperature uniformity and anti-interference ability, all lead to a high accuracy and repeatability data
