In many projects requiring the determination of hydrocarbon contamination, the carbon range distribution, or speciation, of the contaminant is desired. For volatile analysis this involves being able to detect the range from ethane (C2) to dodecane (C12). Due to the broad boiling point range being covered, special considerations must be taken to ensure acceptable and consistent performance.
Air Technology utilizes chromatographic techniques developed at the California Air Resources Board to provide accurate and consistent speciation results.
Table 1 table lists the analytes and reporting limits (RLs) for hydrocarbon speciation for standard analysis.
