A convenient alternative to using liquid argon or expensive cryostats for IUPAC- recommended gas sorption analyses
|Following its well-established tradition of introducing key innovations in the field of porous solids characterization, Quantachrome Instruments is pleased to introduce a novel cryocooling accessory: The CryoSync™ (patent pending). With this compact and deceptively simple accessory, modern gas sorption analyzers can be used to generate isotherms:
It is now well established (see the latest IUPAC recommendations in Pure. Appl. Chem. 87 (2015) 1051)) that argon molecules provide distinct advantages over nitrogen molecules for gas sorption analyses, including the following:
There has been a long-felt need in the art for the means to enable Ar/87K experiments without having to resort to using compressor-based cryostats (which can be very expensive) or liquid argon cryogen (which can also be relatively expensive or even unavailable in some regions). The CryoSync™ fills this need by providing a compact accessory which is easily adaptable to modern gas sorption analyzers. With the CryoSync™ users can easily perform IUPAC-recommended argon sorption analyses at 87.3K using liquid nitrogen (instead of liquid argon) as the cryogen.
