lOO KV SPECTROGRAPH
Like its analytical companion, the multi-element automatic Autrometer, the 1 0 0 KV Spectrograph reflects a new concept in modern, functional design.
Faster a n d more efficient performance u p into the higher atomic number range is now achieved by the new Norelco 100 KV Spectrograph. A constant potential source assures continuous flux at any given voltage. Thus counts with the desired statistical accuracy m a y be accumulated in less time than with conven tional full-wave rectified circuits. The new powerful spectrograph consists of two units. The main assembly is completely shockproofed and rayproofed and incorporates a stepless 0 to 100 K V constant potential generator with 0 to 50 M A current regulation; a goniometer; M A stabilizer and line voltage regulator. The newly designed goniometer is arranged for continuous automatic or manual scanning or may be set for any fixed position for single element determinations. T h e electronic circuit panel contains a scaler-ratemeter, timer, d.c. high voltage supply, high-speed amplifier and a Brown recorder.

In addition, a new Norelco pulse height analyzer may be included. Operation u p to 100 K V permits excitation of Κ lines of heavier elements up t o Radon as well as more efficient fluores cence of the L lines of all the detectable elements from Mag nesium t o Uranium. A n inverted X-ray optical system permits examination of liquid and powered specimens or of solid samples up t o two inches in diameter. Provisions are included for incor porating flow counters and a helium path. The Norelco 100 K V Spectrograph has extended the limits of spectrography inherent in lower powered equipment. As a single example, rare earths—often extremely difficult to dis tinguish by wet analysis—are very readily evaluated through the use of higher kilovoltages.
