This European Standard specifies two methods for the determination of chromium in water by atomic absorption spectrometry. The two methods are covered in separate sections as follows. Section 2: Method A - Determination of chromium by flame atomic absorption spectrometry. Section 3: Method B - Determination of chromium by electrothermal atomization atomic absorption spectrometry.
