Quantachrome Instruments, a
leading manufacturer of materials characterization instruments,
announces the launch of two new versions of its Quadrasorb Surface Area
and Pore Size Analyzer. Already popular with high-throughput industries
like pharmaceuticals and petrochemicals the Quadrasorb has additional
technical features which make it attractive to other
applications. But often those other would-be users don't need
the high-throughput capability. Recognizing and responding to
that need, Quantachrome acted quickly to make 2- and 3-sample versions
available, as well as retaining the original 4-sample configuration.
These new models are nevertheless designed with upgradability
in mind. Should a user of a 2- or 3-station Quadrasorb find
that he really does need the higher throughput afforded by 4 sample
stations, then his Quadrasorb can be upgraded to the full configuration
at some future date.
The attractive technical features of the Quadrasorb include
independent dewars for each sample which affords flexibility of
start/end times for more than one sample, individual pressure
transducers for independent pressure measurements leading to shorter
analysis times, operation in classical helium void volume mode or
patented helium-free mode, and small cold zone (free-space)
volumes for improved sensitivity provided by coolant level
sensors in each station.
