What
do you want in atomic absorption? Simultaneous analyses of two metals ? And compensation for matrix interferences ?
To zip through hundreds of routine analyses ?
Equal efficiency in flame emission and atomic absorption ?
The Jarrell-Ash Dial-Atom II is just the thing for rigorous, routine, day-in dayout use. It's as big in performance as it is easy on
Multi-element analyses without lamp warm-up ?
your budget. Note all these traditionally "expensive" features you'll find on the low-cost Dial-Atom II: Direct concentration readout. Fast dial-an-element wavelength selector. Builtin hollow cathode lamp warmup. Scale expansion to 10X. Flame emission capability.
The hollow cathode lamp turret on the Jarrell-Ash Atomsorb holds up to six lamps on w a r m - u p . To switch lamps, j ust rotate the turret. No waiting. Switching oxidants and lighting the burner, moreover, are just a matter of turning a c o n t r o l and p u s h i n g a button. More pluses: Direct c o n c e n t r a t i o n readout. Two s w i t c h - s e l e c t a b l e gratings. Corrosion-resistant laminar flow burner. Scale expansion to 10X. Flame emission capability.
You'll find analytical capabilities like that only with the Jarrell-Ash Model 800. Its unique dual-channel double-beamdesign makes it the most advanced instrument of its kind. Consider, too, its other high performance features: Digital readout. Signal integration. Scale expansion to 25X. Flame emission.
That calls for the JarrellAsh Model 500. Its exceptional versatility and superb
optics will especially please the researcher. Reasons why: a high resolution monochromator. Selection of eight wavelength scanning speeds. Interchangeable gratings. Unobstructed burner area.
