radioactive components measured as they emerge from the chromatograph I
Pye Radiochromatography Equipment operates with the NEW all-purpose panchromatograph, or any gas chromatograph having a heated column outlet, providing simultaneous records of mixture composition and component radioactivity by the James &. Piper technique. Initial evaluation in leading laboratories shows that future progress in biochemical, biomedical and agricultural research and development will be accelerated by using this tech nique. • Column eluate converted to C 0 2 and H 2 for highest detection efficiency • High signal/ noise proportional counter detects 0.1 millimicrocurie • Peak shape undistorted by small counter volume • Radiochromatogram with eight count rate ranges or integral with six ranges instantly available for maximum quantitation • Continuous background integral automatically zeroed at recorder full scale • Open construction gives maximum accessibility to countertube and flow connections • Radioactive wastes absorbed for safe disposal • Shown above, radiochromatogram of C14 labelled fatty acids, demonstrating no loss in peak shape, reveals additional high activity component.
