A s u m m a r y of the extensive literature on interferences in electrothermal atomization has been prepared by Slavin and Manning (11). Matrix matching and modification d o not o v e r c o m e all chemical interferences. Separation of the elements of interest from the bulk of the sample may be the only practical way to deal with severe p r o b l e m s . Ionization Interferences A t o m s of some elements can b e c o m e ionized in flames or electrothermal a t o m i z e r s . A s a result, the a t o m population diminishes and sensitivity declines.

T h e x-rays emitted by the elements c o m p o s i n g the sample h a v e intensities and wavelengths which are characteristic of the a t o m s of the various e l e m e n t s . T h u s , x-ray emission s p e c t r o m e t r y is a technique that provides both qualitative and quantitative analytical data. The s p e c t r o m e t e r s are capable of measuring both wavelengths and intensities of xrays emitted by the sample. T h e identity of an element emitting a particular line is established by measuring the wavelength of that line and comparing the wavelength with those in tables of standards.

N o n a b s o r b i n g - L i n e M e t h o d In this m e t h o d , the background signal is measured at a wavelength not m o r e than 20 nm from the r e s o n a n c e line. T h e background 30 2. Principles of Determinative Methods a b s o r b a n c e is then subtracted from the a b s o r b a n c e of the sample. T h u s , each sample must be analyzed at the t w o c h o s e n wavelengths unless a dual-channel instrument is being used. T h e line c h o s e n must be a nonabsorbing line of the element being m e a s u r e d .
