Material Characterisation

Thermo Fisher Scientific Pycnometer – Pycnomatic (ATC)

Density measurement is a fundamental parameter required for a full characterization of the properties of solids. It is applicable in a wide array of technological fields such as ceramics, mineralogy, geology, pharmaceuticals, metallurgy, pigments, building materials, foams, plastics, abrasives and catalysts, just to name a few.

Pycnomatic –ATC is the first multi-volume gas pycnometer with integrated automatic temperature control based on built-in Peltier device that dramatically reduces the time necessary to achieve thermal stability of the sample. This enables the user to obtain a very high level of precision in a matter of minutes. Temperature of the manifold is controlled with a precision of +/- 0.01 oC in a range between 18 and 35 oC.

Calibration of the reference and sample cell and the actual measurement are all performed in a closed environment. The sample volume is determined by a mass balance of helium, measuring the gas expansion pressure. Temperature constancy is fundamental in achieving accurate results, especially when the cell volume in use (and thus the sample volume) is very small.

  • Sample Volume Capacity Approximately 20, 40 and 60 cc. (indicative maximum sample cup volumes)
  • Optional sample volume capacity Extra Small (approx.4 cc) and Extra Large (approx. 100 cc)
  • Reference chamber volumes Approximately 20, 40 and 60 cc (indicative calibrated reference chambers)
  • Temperature control range From 18 to 35 oC by an integrated Peltier Device,
  • Temperature sensor number Three
  • Temperature control stability +/- 0.01 oC (in the above temperature control range)
  • Pressure transducer range From vacuum up to 250 kPa absolute reading
  • Purging procedures By continuous flow, gas pulses or vacuum
  • Typical reproducibility & accuracy Better than 0.01 % at 20 oC on sample volume
  • Communication ports Serial port to computer, parallel port to printer for reporting, serial port to balance
  • External gas connections Gas-in port , direct gas-out port and gas-out through restriction.
  • User’s interface Large backlit display, 40 characters x 4 lines, alphanumeric keyboard
