Norelco® ELEMENT ANALYSIS INSTRUMENTATION FOR INCOMING STANDARDS CONTROL, BATCH TESTING, PRODUCTION TESTING AND AUTOMATIC FEEDBACK PROCESS CONTROL X-ray spectrographic instrumentation has become widely used in research laboratories for fundamental research. Because of their accurate, rapid, and reliable response in making qualitative and quantitative elemental analysis non-destructively — these instruments have been pressed into serving many manufacturing fields to assist with their quality control measures. Today, these instruments are used routinely in many industrial applications and processes. As illustrated, the complete X-ray spectrograph consists of three elements : the basic generator, which supplies the X-ray exciter tube ; a cabinet, upon which the spectrographic attachment is mounted ; and an electronic circuit panel. The circuit panel may be fitted with several electronic chassis including a Pulse Height Analyzer for use with scintillation and/or flow-proportional detectors for non-dispersive separation of radiations and improved peak-to-background ratios. Automatic spectrographic instruments are available and include models which are arranged for feed-back control of mixing both solids and liquids. Details are available upon request.

unit.
This versatile instrument may be used with vacuum, helium or air. Other unique features include two detectors (flow-proportional and scintillation) mounted on t h e goniometer a r m p e r m i t t i n g the use of either at its maximum sensitivity over the complete range of detectable elements.
BULK SPECIMEN HOLDER
STANDARD SPECIMEN HOLDER
This exclusive instrument is designed by Norelco for X-ray fluorescence analysis of large slug specimens and can accommodate samples r a n g i n g up to two inches in depth and ten inches square. This facility reduces preparation time and lessens the possibility of specimen contamination.
Houses a high intensity X-ray tube, a radiation-proofed specimen chamber and a specially mounted goniometer. A multi-purpose holder is provided for both liquid and non-liquid specimens. Collimation is selective for eontrolling the dispersion and intensity of the radiation from the specimen.
