Let Us Demonstrate How the Du Pont 310 Curve Resolver Reduces Complex Curves to Component Peaks Quickly and Inexpensively

A one-page advertisement from Du Pont Instruments promoting the 310 Curve Resolver, a compact analog instrument that decomposes complex overlapping curves (from chromatography, electrophoresis, NMR spectroscopy, X-ray diffraction, and similar techniques) into individual component peaks. The operator works directly with the instrument's up to ten function generators to match synthetic peak shapes to the original curve on an oscilloscope screen, with the algebraic sum displayed simultaneously. An optional X-Y plotter and integrator are mentioned for recording and area measurement.

LET US DEMONSTRATE HOW THE DU PONT 310 CURVE RESOLVER REDUCES COMPLEX CURVES TO COMPONENT PEAKS QUICKLY AND INEXPENSIVELY. If you get experimenta! data with overlapping peaks, you no longer have to take computation time to locate them and establish their po- sition, height, width at half-height and area, You don't have to do extra experimentation in hopes of getting better resolution Alt you need is a 310 Curve Re solver and a few minutes. The 310 is a compact instrument you keep right in the lab for immediate use You operate the 310 without making computations. Yet you can use it to analyze raw data from chromatography, electrophoresis, spectroscopy, ultracentrifugation, x-ray diffraction, NMR spectros copy, counter-current extraction, and other analytical techniques — any plotted data in some form of distribution curve it's much more convenient to use than a digital computer. Far less expensive. And generally faster in terms of total time because you | Elect: opherews gatte ce! mone! Blood serun 1eso eed flo cis compotestt oa the 319 don't have to program the 310 and because you work directly with it, as part of the computation loop. You constantly examine and modify the number, positions end shapes of the peaks as the instrument bulids them up and displays their algebraic sum, To use the 310, you put the curve you want to analyze (a chro- matogram, for example) on the | Rew | led Gata (an IR spectrum of poly | ‘iryiene im ites case) 6 placed on dest tes (1), reflected on scape tace (7).

It's reflected on the screen on an 18-inch oscilloscope, located right in front of you. Next, you turn on the “peak shapers,” or function generators the 310 has as many as ten of them), with the controls on the front of the console. The function generators cause peak snapes to be displayed on the oscilloscope superimposed with the image of Pyrelyss cl eevatograrn of a Capolyree: fesolwed rite (14 fee Comeooments on the 210 your original curve. With the con- trols, you move the peaks and ad- just their heights and widths until their algebraic sum matches your original curve. (You can also skew peaks, invert them or slope base- lines.) That's essentially all there is to operating the 310, Examine the original peaks right on the oscillo- scope. Evaluate the “goodness of tit’ between experimental! and syn- thetic curves. Record the peaks, to- gether with the sum curve, on an optional x-y plotter and read their relative areas on the integrator. We would like to demonstrate the Du Pont 310 Curve Resolver right im your lad or office. in fact, we could cemonsitrate with some of your complex curves.
