ACD/Curve Manager

Full List of Features

  • Read data from single-, dual-, or multi-column ASCII files with an ASCII import wizard.
  • Export your analytical curves in ASCII file format.
  • Expand the list of supported import/export formats with your own custom external converters (DOS executable (*.exe) or ACD/ChemBasic programs (*.bas)).
  • Review processing steps for your curve data with the History file (full audit trail).
  • Calculate onset, end point and mid point for TGA data.
  • Calculate heat of enthalpy for DSC data.
  • Attach chemical structures to your analytical curves in order to better identify and interpret them. Find data files through organic, polymeric, inorganic, organometallic, and generic Markush structure searches.
  • Organize and compare multiple spectra in Tile, Full, or Overlay (series) modes.
  • Customize curve colors, axis names, and directions.
  • Capture analytical curve interpretations from the analysts more fully through the use of multiple annotation layers.
  • Interactively zoom in on any part of the curve.
  • Create customized data entry dialog boxes with Data Forms Manager to facilitate data input.
  • Create professional high-quality reports in PDF and ACD/ChemSketch formats, and more.
  • Automate repetitious processing tasks with macro commands, which can be applied later to a series or single curve.
  • Perform various X- and Y-axis conversions through standard mathematical operations with the transform tool
  • Calculate derivatives from the 1st up to the 4th order derivative and overlay it above the curve for analysis, or permanently convert the curve to the given order.
  • Apply baseline correction to a curve or series of curves automatically.
  • Subtract a curve scaled by a given factor from another curve.
  • Interactively remove noise from the data with flexible FFT or Savitsky-Golay smoothing algorithms.
  • Standardize the apparent resolution of a curve to that of a lower or higher resolution instrument, or to produce uniformly-spaced data sets.
  • Model spectrum or spectrum-like curves with a sum of analytic peak functions (Gauss, Lorentz, Gauss+Lorentz mix, LogNormal, Pearson VII).
  • Pick the peaks and inflection points on the curve automatically or manually. These peak positions are automatically entered in a table of peaks.
  • Calculate peak areas and FWHH (full width at half-height).
  • Create straight lines overlaying experimental curves manually or building linear regression on the selected part of the curve. Move and rotate lines. Find intersections of a pair of lines and the middle point of a line segment between two other lines.
  • Annotate curve regions, peaks, or characteristic points.
  • Fit the data with a straight line or polynomial, making use of a powerful and interactive regression tool.
  • Link data from related techniques in a clear hierarchical system
  • Link live curve data to a single data point or peak within a chromatogram, spectrum, or another analytical curve.
