ANALYSIS OF ALKALINE AND ALKALINE EARTH METALS IN STANDARD SAMPLES BY LIQUID ELECTRODE PLASMA OPTICAL EMISSION SPECTROMETER
ABSTRACT: Sodium, potassium and calcium in
standard sample solution were
analyzed with a portable analyzer of
liquid electrode plasma optical emission spectrometer (LEP-OES) to assess its validity for quantitative
analysis. Reproducibility and
sensitivity were investigated
using different disposal
sample chip and applied
voltage. ln the applied voltage of 800 V, there is no increasing period of emission
intensity by consecutive
measuremenl and the
relative standard deviation among
chips was less
than 20%. The sensitivity of
emission intensity for
Na and K were
proportional to the
applied voltage, but Ca was
exponential. The sensitivity
was different by
kinds of element
and applied voltage.
According to its reproducibility, the spectrometer would be used
for quantitative analysis.
