(c) Expansion of Y Axis
Numeric values should be input to specify a desired expansion range
for the ordinate.
Smoothing
A spectrum with a large noise level can be corrected to form a smooth curve.
Differentiation
The data of a spectrum currently displayed on the LCD are differentiated.
The derivative order applicable ranges 1.
Integration
A peak area can be determined by specifying the two wavelengths or times
between which you wish the integration calculated. The DB-20 then
integrates the area under the spectral curve between the specified points and
points out the results.
Calculations Between Spectra
You can calculate addition, subtraction, multiplication or division between
two spectra or calculate a constant value with the resulting data displayed
on the LCD.
Recalculation During Rate Assay (Kinetics)
Upon completion of a rate assay in the Time Scan mode, you can adjust the
calculation start time and end time to allow recalculation of the data.
2.4.5 Data Storage Function
The following data are stored in the memory, and are not deleted even if the
instrument power is turned off.
Analytical conditions for 20 tests
The working curve prepared for each test can also be stored together with
the analytical conditions.
Up to 10 measurement results in inside memory. You also can store the
measurement results in flash memory which can be open via personal
computer.
Three baselines (System baseline and two user-defined baseline.)
Instrument parameters that were used most recently.
