How It Works
This analytical technique is commonly known as “arc spark spectrometry”.
This is because it uses a short pulse of electrical spark to transfer energy
to the atoms in the metal samples, which in turn emits lights that are
characteristic of the material. This information is used to identify its
chemical composition. The intensity of the light is indicative of the
concentration of the material within a sample. With standard samples
available, a calibration curve can be developed to measure the PDA-7000
concentration accurately.

Optical emission spectrometers use diffracting grating to diffract the
wavelengths of light before they reach detectors. As there is an array of
detectors, an analysis of tens of elements can be performed within a
minute. Optical emission spectrometers typically are capable of low
detection limit. In Shimadzu’s optical emission spectrometers, various
unique features, such as the time-resolution analysis and pulse distribution
analysis (PDA) photometry, make them the most sensitive and precise
OES on the market. PDA-5500 S
