NOTE: Submit as a separate sample. When analysis of a compound is requested, an elemental analysis is performed and reported as the compound. The analytical method does not distinquish between dust and fume. If the gross weight of the sample yields a concentration below the standard for the air contaminant, do not submit the sample to SLTC for analysis.
