Feature Description
Mode Specifies Scan or Fixed data acquisition.
Data mode Y-axis format for acquired data.
For Abs*Factor (Scan only), set Factor to a value by which to
multiply measured absorbance values.
Smooth (Scan only) Select the desired degree of smoothing (if available for the
selected data mode and Derivative setting). Smoothing reduces
noise in the data but can also remove some spectral features
such as small peaks, valleys and shoulders. See About
Smoothing.
Derivative (Scan only) Select the desired derivative order for acquired data (if available
for the selected data mode).
Start wavelength and End
wavelength (Scan only)
Starting and ending values of the wavelength range for
acquiring data.
Bandwidth A larger spectral bandwidth increases the amount of energy that
passes through the sample. Increasing the bandwidth can
improve the signal-to-noise ratio; however, a larger spectral
bandwidth decreases the ability to resolve closely spaced spectral
features.
Integration time How long the system acquires and averages data at each data
interval (for Scan) or at each measured wavelength (for Fixed).
Increasing the integration time improves the signal-to-noise
ratio but reduces the scan speed.
Data interval (Scan only) Difference in wavelength between two consecutive data points.
Scan speed (Scan only) Wavelength range covered per unit time. Varies inversely with
integration time. Increases as the data interval increases.
Estimated time (Scan
only)
Estimated duration of data acquisition. Increases as integration
time increases and as the data interval decreases. Varies inversely
with scan speed.
Table of wavelengths
(Fixed only)
Shows the analysis wavelength(s) entered on the Measurement
tab.
