8.4 Equipment faults and analytical problems
Other problems not detected by the system monitoring can also occur. Starting a
measurement is possible. Such errors are usually detected on the basis of implausible
measuring results (analytical problems) or are clearly visible in the equipment
technology.
If the suggested solutions are not successful, inform Service.
Error
Water traps clogged
Cause Remedy
Lifetime exceeded (renewal after 6 month
recommended, matrix dependent)
Measuring of samples with strong aerosol generation
Replacement of the water traps (see section "Replacing the
water traps" p. 69)
scattering measured values
Cause Remedy
Filling of combustion tube depleted Perform catalyst change
metering faulty Check metering
Check the syringe volume (check syringe label and entry in
multiWin (menu command C
ONFIGURATION EDIT OPTIONS,
tab A
NALYZER COMPONENTS, list SYRINGE SIZE))
Cannula damaged Exchange cannula
Use a cannula suitable for particles if the substance
contains particles
inhomogeneous sample matrix Warm up cold samples before analysis
filter samples prior to analysis
stirring insufficient stir particulate samples, for measurements with sampler
adjust stirring speed in multiWin under METHOD EDIT
PROCESS PARAMETERS STIR
Sensitive samples prevent introduction of CO
2
or organic vapors from the
ambient air
cover sample cups on sampler with aluminum foil
Aerate the head room of the sample container for manual
measurements
Check the environmental conditions
Remove the source of interference
Drift NDIR basic
unsuitable integration criteria
Measurement is cancelled to early
Check the settings
Increase the maximum integration time
Low results; all areas
Cause Remedy
Catalyst depleted Exchanging the catalyst
System is leaky Check the lock for tightness or replace the septum
