Five-station Helium Porosimeter
A new line of gas pycnometers, analytical instrumentation for characterising properties of powders and porous materials, includes a high-throughput five-station version named the Pentapycnometer
The Quantachrome Instruments line of gas pycnometers for the measurement of true density of solids includes a high-throughput five-station version named the Pentapycnometer In the exploration industry, gas pycnometers are also called helium porosimeters because, more often than not, helium gas is used to penetrate all open and connected pore space in rock and core samples

Quantachrome Instruments announces their Autotap analyser for tap density of powders with a keyed lock to prevent unauthorised changes to the proper number of taps, to ensure conformance to SOPs
Catalyst characterisation analysers
Both of the Quantachrome Instruments catalyst characterisation units, the Autosorb-1C-TCD and the ChemBET-3000, feature stable, oxidation-resistant detectors for characterising carbon contents
The Pentapycnometer features automatic replacement of atmospheric gases by helium gas in a series of "gas-rinse cycles" or timed flows of purge gas.
Sample ID entry and analysis parameters are keyed in via the membrane keypad and results are available directly to printer or via upload to custom PC software.
A serial port balance interface is included as standard, as are fifteen sample cups and a set of stainless-steel calibration spheres.
The Pentapycnometer occupies less than 3 sq ft of bench space yet is capable of multiple, repeat analyses on up to five samples completely automatically.
Sample cells are optionally available in stainless steel for added durability.
A temperature-controlled version which uses an external circulator bath and a remotely operated version are also available.
The Pentapycnometer is just one of the Quantachrome gas expansion pycnometers which all use the expansion of dry inert gas, according to Boyle's Law, to determine the solid volume of porous samples.
Quantachrome Instruments, founded in 1968, is a world leader in the design and manufacture of analytical instrumentation for characterising properties of powders and porous materials.
Dedicated to providing the highest quality scientific instrumentation, Quantachrome has more than 50 sales, service and distribution offices worldwide!.
