40988 - iCAP 7000 - Application Note


The analysis of transition metals and their alloys have always been a challenge to optical spectrometry due to their spectrally rich matrices. Titanium, like iron and tungsten, has many emission wavelengths and will cause excessive spectral interference problems in instruments with inadequate resolution optical systems. On lower resolution ICP-OES Spectrometers, peaks will more readily interfere and overlap with one another. In severe cases only one peak is seen, and thus a high-resolution optical system is essential. Coverage of a wide wavelength range is also an added advantage since some primary element wavelengths will show spectral interference. Since it is generally best to avoid a spectral interference than to correct for it, the power of having comprehensive wavelength coverage is essential for optimum analysis of alloys.
