They may vary depending on specific analytical needs. <br /> z Sceening method for soils <br /> 3 MTBE can be analyzed with U.S. EPA SW-846 Method 8015 or 8021, however, 8021 has lower detection limits, is subject to less <br /> interference in highly contaminated samples, and tends to be more economical by providing BTEX data in the same analysis. Concerns <br /> about coelution with some alkanes requires at least one confirmitory analysis with SW-846 Method 8260 per site. <br /> 4 See Chap. 4 of SW-846 for specific appropriate methods. <br /> 8 8021 replaces 8010 and 8020. <br /> 8 The old method, 8240, is replaced by 8260. <br /> This method is similar to 418.1, however, perchlorethane (PCE) is used as an IR solvent instead of Freon-113. <br /> 8 418.1 is used extensively although it is not on the list of promulgated methods. <br />
