No, it's not handsome.
Fed up with TOO LITTLE, TOO LATE IR Spectroscopy? FTS™ Systems (Fourier Transform
Spectrometers)
using B l o c k . E n g i n e e r i n g Michelson interferometers are up to 1,000 TIMES more sensitive . . . take measurements in one minute!
But you can depend upon it to collect fractions. People have for years! The AO Automatic Fraction Collector has compiled an impressive record of accurate, reliable, and reproduc ible p e r f o r m a n c e in thousands of laboratories. Some units have been on the job for 10 years! We could face-lift it, but why? That would just cost you more. This tough old workhorse can col lect equal, p r e d e t e r m i n e d , liquid samples by three methods — volu metric s i p h o n i n g , timed flow, and drop counting. Use test tubes, cul ture or centrifuge tubes—as many as 240 at once! A variety of accessor ies permits an exceptional range of applications. For details, contact your distributor or write to us.
Model FTS -12 with Block Engineering Interferometer Spectrometer • 0.3 to 40 microns • Rapid Scan, Moderate Resolution • Digital or Analog Readout, interfacing with any computer • Hand-held optical units for lab or in-situ measurements
Model FTS -16 laboratory research instrument for the FAR IR Regions • 25 to 3,000 microns • High Resolution • Liquid, Gas, Solid Sampling • Digital Data System, interfacing with in-house or time-shared computer Model FTS""-14 with Block Engineering Model 296 research Spectrometer • High Resolution, to 0.5 c m " 1 • Measurement times reduced to a fraction, without loss of sensitivity • Wavelength accuracy and repro ducibility better than 0.1 cm-1 • Constant resolution throughout entire spectral range, 2.8 to 15 microns • Stray light less than 0 . 1 %
These are the most advanced, yet easiest to handle, spectroscopic instru ments available. Now you can couple routine measurements with many analytical tasks far byond the capabilities of slow-scanning, insensitive (and immobile) monochromators.
