SGE* ms-NoVent* 5-minute GC/MS Column Changeover System
Change columns in 5 minutes instead of 5 hours. ms-NoVent* allows immediate use of the mass spectrometer after a change by elimination of air through a helium purge system and by restriction of helium flow into the MS to a level which can be handled by the MS pumping system. ms-NoVent is available for Varian*, Shimadzu*, Finnigan and Agilent* GCs. Restrictors must be ordered separately.
" First time installation requires adapter; subsequent replacements require restrictor only.
