26 SPECTRO ARCOS FHX22 —
5.5 Carrying out the measurement
5.5.1 Preparing the measuring procedure
Before starting the measurement, proceed as follows:
1. Ensure that the wavelength calibration has been performed.
2. Proceed with a calibration; if required, see page 28.
3. Check the safety measures if you work with hazardous or corrosive samples.
The instrument is now ready for measuring samples.
Wavelength calibration of the optical system
The wavelength calibration of the optics is mandatory:
after a software message (wavelength drift).
after it has been switched on and after the temperature stabilization.
before setting up a new method.
before proceeding with high-precision measurements.
I. Aqueous applications
The wavelength calibration of aqueous applications requires a solution of the
following composition:
Element Concentration mg/L Element Concentration mg/L
Ca 1 Eu 10
Be 2 In 10
Li 2 K 10
Sr 2 Ni 10
Mn 5 P 10
Mo 5 Si 10
Na 5 Ti 10
Sc 5 V 10
Ce 10 Y 10
Cu 10 Zr 10
Fe 10 S 50
