Unformatted text preview: An animation describing the double dispersion inductively couple plasma spectrometer is detailed here www.shsu.edu/%7Echm_tgc/sounds/ICPwCCD.mov . Unlike atomic absorption spectrometry (AAS), the power of inductively coupled plasma spectrometry (ICP) lies in its ability to simultaneously disperse and detect many of the emission lines from the elements in the sample. Earlier versions of this instrument used a grating and multiple photomultiplier tubes arranged in the so-called Rowland Circle. An animation displaying a version of this design is available at www.shsu.edu/%7Echm_tgc/sounds/ICPwRC.mov . Most modern ICPs used a combination of two dispersion devices to separate sample emission from the plasma. In the design shown here a grating and a prism disperse light into a two dimensional image that is focused onto the detector, a charged couple device (CCD). In the example here I'm showing this instrument running in a single element mode . Although only a single element is emitting in the plasma, it contains multiple lines and the wavelengths of those emissions are shown in the image in the...
