Function
The SPECTRO ARCOS FHX22 is an automatic optical emission spectrometer
providing simultaneous measurements. It uses inductively-coupled plasma
excitation and a semiconductor-based detector system for quantitative and semi-
quantitative analysis of liquids.
The liquid sample is nebulized and fed into the plasma as an aerosol. The high
temperature of the plasma (6000–8000 K) evaporates the sample. The molecules
contained in the sample dissociate into atoms. The atoms are excited and partly
ionized.
The excited atoms and ions emit an element-specific radiation. A transfer optics
feeds this radiation into the optical system.
The emitted radiation is diffracted into its spectral components in the optical
system. The intensity is measured using semiconductor detectors (CCD).
After processing the measuring signals in the instrument, the measured element
intensities are evaluated by the Smart Analyzer software.
Methods are set up prior to measuring. Calibration functions for each element to
be determined are stored in these methods. Concentrations are calculated from
the measured intensities, using these methods. The concentrations are displayed
on the screen. They are also printed on a printer (can be activated as required) or
saved in a database.
