Double Beam Wavelength Scans

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 430nm wide to be viewed.

Dynamic Scan Recall

The last 20 or more 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 eight 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 fourth 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.

Programmed Scans

Automatic scans, single or repeat may be made of a cell program of up to 4, 6 or 8 cells. A programmed sequence of scans may also be made of a single sample.

Time Course Plots

Changing samples or flows may be examined and displayed by making a time course plot. Data may be reprocessed and stored, security code protected, with an automatically assigned recall number.
