in Table 1 for soil and sediment samples. Some common elements are not listed in Table 1
because they are considered "light" elements that cannot be detected by field portable x-ray
fluorescence (FPXRF). They are: lithium, beryllium, sodium, magnesium, aluminum, silicon, and
phosphorus. Most of the analytes listed in Table 1 are of environmental concern, while a few others
have interference effects or change the elemental composition of the matrix, affecting quantitation
of the analytes of interest. Generally elements of atomic number 16 or greater can be detected and
quantitated by FPXRF.详细>
