Interference table
Specialist : System edit: Interference table
Interference tables (IF-Tables) are used to correct overlapping spectra.
• Additive interference tables (e.g. for overlapping spectra)
• Multiplicative interference tables (e.g. for dilution effects).
The interference tables are assigned to the components in “
System edit: Calibration data ”
and automatically calculated - if a mark is set.
4 interference tables per component can be calculated. Default assignment (the
assignment can be changed):
The first 3 tables are used preferably for additive IF, the 4 th table is used for multiplicative
IF.
Additive interference
The spectra of the components are overlapping. The interference can be calculated by
subtraction of the interfering component. For this purpose, the interfering component must
be measured at another place of the spectrum which is free from the influence of further
interferences. This influence is corrected by the additive IF-Table.
Multiplicative interference
The absorbance coefficient of the sample component is influenced by the interfering
component. The interference is compensated by a correction factor. For this purpose, the
interfering component must be measured at another place of the spectrum which is free
from the influence of further interferences. This influence is corrected by the multiplicative
IF-Table.

Number of table.
The name is identical to the name of the component which this table is assigned
to (in “ System edit: Calibration data ”).
IF-Component Component number and name (from Specialist: System edit: Definition of
components ) of interference component
IF-Type additive or multiplicative.
IF-Signal Absorbance or concentration, dependent upon what is to be entered.

Mark (  ) Mark (  ) = calculate.
If no mark is set, then the pair of values is inserted at the end of the table and not
calculated.
Absorbance Absorbance of sample component. Enter manually.
IF-Component Enter IF-Absorbance/Concentration, depending on what is indicated in
“IF-Signal” (see above)
Key assignment:
Shift F5
Display actual value (in Abs. or Conc., depending on IF Component).
<ENTER>: Accept displayed value.
F8 Represent linearization curve graphically.
The numerical display corresponds to the pairs of values from the table.
Key 3: Change scales.
