ALPHAGAZ 1000 provides the same specifications as ALPHAGAZ 1, but is offered for those applications requiring cryogenic liquid argon, nitrogen and helium. Since large volumes of gaseous nitrogen or argon are needed for ICP and FTIR instruments, cryogenic supplies can be better suited than cylinders of compressed gas to fill this need. Liquid helium is often used to cool magnets in instruments such as NMR spectrophotometers.
