Method procedure

FOI

Selection:
none | dye/kb | pmole/
μg

Only for the

Dye labels method group.

Display of the FOI in addition to the result of the sample
measurement.
The FOI (frequency of incorporation) is a measure for the
number of dye molecules per nucleic acid molecule that are
integrated into the nucleic acid. Units are "dye/kb" (dye
molecules per 1000 bases) or "pmole/μg" (pmol dye per μg
nucleic acid). "None": no FOI calculation.

Background

Selection:
on | off

Prior to the calculation of the results of a sample the
absorbance of a background wavelength, during which the
analyte to be measured should exhibit the absorbance value
zero, is subtracted from the absorbance of the measuring
wavelength. Frequent application: Partial correction of
turbidity for measurement of nucleic acids (background
wavelength in this case: 320 nm or 340 nm).

Wavelength

Wavelength in nm.
Range: 200 to 830 nm.

Wavelength at which the background is to be measured. The
analyte to be measured should have the absorbance value zero
in pure form here.

Background for
dyes

Selection:
on | off

Only for the

Dye labels method group.

Application of the background correction to the measurement
of a dye (see

Background parameter).

Wavelength

Wavelength in nm.
Range: 200 to 830 nm.

Only for the

Dye labels method group.

Wavelength at which the background for the dye is to be
measured. The pure, not contaminated dye to be measured
should have the absorbance value zero for this wavelength.

Autoprint

Selection:
on | off

Printing a measuring result immediately following
measurement with the thermal printer.
Only the main result data will be printed. To output detailed
data, the required data packets can be compiled and printed in
the

print & export method step at the end of a measuring

series.

Wizard: the wizard at the top of the display will take
you through the method procedure. The currently
active method step is highlighted.
