PAPER RADlOCH ROMA-TOG;RAPHY. SPEED UP YOUR PAPER RADlOCH ROMA-TOG;RAPHY. SPEED UP YOUR PAPER RADlOCH ROMA-TOG;RAPHY. By a factor of up to six. How? With Nuclear-Chicago's new Digital Actigraph? Ill-the fast digital/analog paper-strip radiochromatography system. It's designed for speed and reliable, quantitative data. FAST BETWEEN PEAKS For example, Digital Actigraph 111 automatically senses low-activity areas between peaks. Then it stops counting and speeds up the paper strip and the recorder

This acceleration is particularly advantageous for widely-spaced radioactive fronts or for strips that require slow scan-speeds due to their low activity. ACCURACY, TOO Digital Actigraph II has a built-in digital rate-gate and exclusive pulse-stepped drive motors. These features ensure that deceleration and resumption of counting upon entering a peak are virtually instantaneousessentially no counts are lost. All of which makes it possible to sense activity peaks with better than 97% accuracy in most cases. PLUS DIGITAL INTEGRATION This new paper-strip radiochromatography system also incorporates a fast digital integrator, which automatically quantitates the activity in each individual peak. And it prints out this data with virtually no loss of counts during printout. It'll also print out a running subtotal of the peaks, if desired. HOW ABOUT TLC? Is your interest thin-layer radiochromatography? The Digital Actigraph 111 is easily adapted for that kind of work too.
