Tab: Method ▶ MEAS Opt Conc ▶ Properties... ▶ MEAS Opt Conc - 'Command
name' ▶ Measuring parameters
Command name
Name of the command.
Entry 25 characters
The parameters for the measuring procedure can be defined on this tab.
Tab for Avantes spectrometer
Wavelength
Wavelength at which the measured quantity (absorbance) is recorded.
Input range 100.0 - 2,000.0 nm
Default value 400.0 nm
Blank value
Value by which the measured quantity (absorbance) is corrected. Here an
expression can also be entered through the formula editor (e.g. xx.EME
from other measuring command) by which every measured absorbance
value can then be corrected.
Input range –1E+12 - 1E+12 (max. 10 digits)
Default value 0.0
Entry 1 - 10 characters
Selection mol/L | mmol/L | µmol/L | g/L | mg/L | µg/L |
mg/mL | µg/mL | ppm | % | mEq/L
Default value ppm
Integration time
Integration time for absorbance measurement.
Input range 0.01 - 600,000 ms
Default value 6 ms
Averaged spectra
Number of spectra that are recorded and averaged.
Input range 1 - 10,000
Default value 10
Smoothing
Number of neighboring pixels with which the light intensity of each mea-
surement pixel is averaged.
