1These are the standard methods of preparation for the corresponding method. They may vary depending upon specific analytical needs.
2Screening method for soils.
3MTBE can be analyzed for with U.S. EPA SW-846 Method 8015 or 8021, however, 8021 has lower detection limits, is subject to less interference in highly contaminated samples, and tends to be more economical by providing BTEX data in the same analysis. Concerns about co-elution with some alkanes requires at least one confirmatory analysis with SW-846 Method 8260 per site.
4See Chapter 4 of SW-846 for specific appropriate methods.
58021 replaces 8010 and 8020.
68260 replaces 8240.
7This method is similar to 418.1, however, perchlorethane (PCE) is used as an IR solvent instead of Freon-113TM.
8418.1 is used extensively, although it is NOT on the list of promulgated methods.
