Self-configuring gas analyzer

    Nov. 1, 1995
    A residual gas analyzer uses microprocessors in the sensor head that allow it to reconfigure firmware when software changes are detected, thus eliminating the need to change EPROMs. The Sapphire smart-head residual gas analyzer`s drive electronics are housed in a compact module that attaches directly to the quadrupole analyzer to provide noise immunity. The instrument can detect masses ranging from 1 to 300 amu and includes a charge-integrating signal amplifier for sub-part-per-million gas ident
