It's unique. It's the completely new Bendix® MA-1. It gives you both fast scan and high sensitivity. (How's that possible? It uses the new, exclusive, bakeable magnetic electron multiplier.) Yours, too: Simultaneous scope and recorder readout. MA-1 is a complete system. Its l-to-500 amu operating range permits application in both organic and inorganic research. This means that for $10,500, you get a Time of Flight Mass Spectrometer that makes other lowcost models seem incomplete. With a 50,000 spectra-per-second oscilloscope scan rate. 1.5 seconds to 60 minutes recorder scan time for 2 to 200 amu. Resolution greater than 200. Mercury diffusion pump that gives operating pressure below 10~5 torr and, with addition of liquid nitrogen trap, to 10"8 torr. Stability of + 1 % per hour on a permanent gas peak. Analyzer assembly bakeable to 300°C. You'll find MA-1 particularly useful for examining short duration samples. Gas chromatograph effluents, for example. Its basic inlet system is suitable for direct sampling of volatile liquids and gasses, and for direct coupling to gas chromatographs. Electronics? Table-top, integrated, solid state circuits for trouble-free performance and easy maintenance.
