X-my spectrography — with GE's X R D ^ S ^ - ^ ^ · · * 4 * ^ will give you fast, accurate, direct quantitative analysis There's no guesswork when you handle quantitative analyses with the G F XRD-3S x-ray spectrometer. Take any sample — you get a direct chart record of composition by clement in the 22-97 range. Accuracy is maintained over a wide range of concentration — from hundreths-of-a-percent to 1 0 0 % . It's fast — only one to five minutes per element — and non-destructive. Basis for this outstanding performance is GE's patented curved f o c u s i n g mica crystal.
