NEW MODEL 8 8 0 : THE FINEST GAS CHR0MAT0GRAPH BUILTAND WE'RE READY TO PROVE IT! Here's the new gas chromatograph that stands as the sum o f Perkin-Elmer's twelve years of development and manufacture in gas chromatography: the M o d e l 880. The M o d e l 880 most closely meets the research and routine requirements o f the user,- it's the instrument shaped b y your needs, your comments, your criticisms. A d d up these benefits: BUILT-IN RELIABILITY: • Easy service—all parts accessible, a n d
readily removable. N e w dual flame and hot-wire thermal conductivity detectors... and a new electron capture detector, ruggedly built to the exacting standards you asked for. • A modern, solid-state, electrometeramplifier— providing reliable unattended operation, particularly when coupled with today's electronic digital data a n d integration systems. ANALYTICAL VERSATILITY • Initial isothermal period control, with a new multi-purpose dial-controlled timer. • Controls for both hydrogen and helium flows, hydrogen individually controlled to e a c h side o f the d u a l flame i o n i z a t i o n detector. For capillary column operation,' t h e r e ' s a s w i t c h - o p e r a t e d helium f l o w control· bypass.
• Improved gas sampling valve: extremely low d e a d volume, with one valve serving either column. A d d the a l r e a d y - p r o v e n features o f Perkin-Elmer gas c h r o m a t o g r a p h s : d u a l columns, packed or capillary—dual differential detection — linear temperature p r o g r a m m i n g t o 4 0 0 ° C — thermally stable, high-velocity circulating air Dynathermal oven—fully-proportional oven temperature control — and you have an instrument that can't be overlooked when you're shopping for G C hardware. If you require o n column injection and glass columns, with all the features of the M o d e l 880, specify Perkin-Elmer M o d e l 8 8 1 .
