INDUCTIVELY COUPLED PLASMA -OPTICAL EMISSION SPECTROMETER(ICP-OES)
Make: Agilent Technologies
Model: 700 series ICP-OES
ICP, abbreviation for Inductively Coupled Plasma, is one method of optical emission spectrometry. When plasma energy is given to an analysis sample from outside, the component elements (atoms) is excited. When the excited atoms return to low energy position, emission rays (spectrum rays) are released and the emission rays that correspond to the photon wavelength are measured. The element type is determined based on the position of the photon rays, and the content of each element is determined based on the rays' intensity.
When we dissolved solid sample with the above procedures, filter the dissolved sample through Whatman filter paper. The sample solution pH<2.0 kept before going to the instrument.
Determination of cadmium spectra
· Low detection limits
· Multiple elements
· Limited spectral inferences
· Good stability
· Low matrix effects
· Liquid samples only
· Maintenance cost is high (Argon gas)
