Limas11: Notes for Calibrating,
Limas11 with Internal
Cross-Sensitivity
Correction
Wait Until End of
Warm-Up Phase
8-C-6
During calibration cross-sensitivity and / or carrier gas corrections by other meas-
urement components are switched off. Therefore, the following notes should be
observed:
For zero-point calibration all sample components must be calibrated in the
following sequence:
• First that sample component which is not corrected,
• Afterwards that sample component which is affected by the smallest number of
corrections,
• Up to that sample component which is affected by the largest number of
corrections.
Example:

Cross-sensitivity correction
Sequence for zero-point calibration
For end-point calibration likewise all sample components must be calibrated. In
doing so, a corrected sample component should be calibrated only using a test
gas containing no components which cause cross-sensitivity, i.e. consisting only
of the measurement component and an inert gas like N
The Limas11 analyzer module should only be calibrated after the warm-up phase,
i.e. approx. 1.5 hours after connecting the power supply.
