N o w you can speed routine analyses photoelectrically, a n d still solve tough " o d d s a m p l e " o r research problems photographically — all with the same versatile instrument. N o " a t t a c h m e n t s " t o m o u n t . . . n o tedious realignment. With the t u r n of a single control you can convert from full-range spectrographic analysis t o high speed direct-reading analysis of as m a n y as 20 elements simultaneously. With the Jarrell-Ash 3.4 Meter Convertible Ebert Spectrograph, you'll enjoy flexibility that lets y o u tackle a greater variety o f materials . . . analytical range to ferret o u t unsuspected trace elements . . . speed to handle m o r e samples per h o u r — keep quality control in step with p r o d u c t i o n . A n d a d d t o these the footstep-saving convenience o f a single basic instrument with all controls centrally grouped.

2:15 p.m.
Simple, trouble-free optical system — automatically in focus at all times.
MAGNETIC RESONANCE
Direct reader dials compute during exposure — results can be read the instant ignition stops. Single grating delivers full 20" of stigmatic spectrum. Available as conventional spectrograph only, with provision for easily adding direct reader section later if desired.
