Curve and Line Fitting

A straight line, quadratic or cubic curve may automatically be fitted to a set of up to 30 standards. Fits may be made with an intercept or forced through zero. Replicate standards may be used for any given concentration. All entries are prompted for simplicity of operation. A quadratic curve fit is shown here.

Curve Editing and Storage

Suspect standards may be observed by inspection of the screen display and either deleted or substituted by a replicate standard.

Up to 30 curves may be stored in integral memory, security code protected for future use.

Derivative Spectra

Derivative spectroscopy is a powerful technique for revealing hidden information or enhancing fine detail in a spectral scan. Bands masked by other overlapping bands or distorted by a sloping background may be accurately located for quantification. Derivative plots may be displayed on their own or superimposed on a wavelength scan, with or without an offset. The degree of smoothing used is operator entered and ranging is normally selected to be automatic.
