Scans at up to 4000nm/min are presented on screen or printed with all peaks annotated with wavelength and Absorbance. Tables are also presented listing all peaks and troughs with values.
Display Scrolling
Use of the display scrolling facility enhances the effective screen size and enables spectra and data up to 550mm wide, 6 screen widths, to be viewed. The last eight scans are automatically retained for recall by entering their scan sequence number and may be reprocessed, overlayed or transferred to protected memory for future recall.
Overlayed Spectral Scans
Up to six scans, including stored scans, may be overlayed, with or without offsets for convenient comparisons or further manipulation.
Difference Spectra
New wavelength scans or scans from store may be presented on screen and the difference spectra produced. The scans may be normalised enabling spectral stripping to reveal impurities or additives.
Derivative Spectra
Derivative spectra, up to sixth are readily produced, with selectable smoothing, either alone or superimposed on the fundamental, with or without an offset. Scaling is automatic with all peaks and troughs quantified.
Scan Storage
Up to 100 spectra may be stored in 10 safe memory banks for future recall. Each spectrum is automatically allocated a recall number, when stored, and may be security code protected against tamper or deletion.
