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.

Suspect Standards and Curve
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.
