DISCLAIMER

Methods

Analytical methods and procedures in this compendium have undergone systematic interlaboratory studies to determine the performance characteristics for the intended analytical application. AOAC INTERNATIONAL members and other volunteers have reviewed the analytical results and determined that a particular method is appropriate for the analyte and matrix stated, provided the analysis is conducted by a competent analyst as written. No warranty, implied or expressed, is made by AOAC INTERNATIONAL on the methods described, their safety, or products mentioned. AOAC INTERNATIONAL, its members, and nonmember volunteers who have aided in the development and validation of methods included in this volume assume no responsibility for any economic, personal injury, or other damage that may occur to individuals or organizations because of the use of these methods.

Commercial Products

Names of manufacturers, suppliers, and trade names are furnished solely as a matter of identification and convenience and reflect the conditions within which each method was developed in the originator’s laboratory. Inclusion of this information does not imply AOAC promotion, approval, endorsement, or certification. The same or equivalent products, instruments, supplies, apparatus, or reagents available from manufacturers and suppliers other than those named, or other brands from other sources, may serve equally well if proper validation indicates their use is satisfactory.

WARNING

Always use fume hoods, proper ventilation, and protective clothing and equipment when required.

See Appendix B, "Laboratory Safety," for further information on safety.

REFERENCING AOAC^® OFFICIAL METHODS^SM

Each AOAC^® Official Method^SM has its own permanent method number that is part of the title block. The paragraph number located in the upper left is only a locator number and not the method number. For example:

999.11 is the permanent number of the method and 9.1.09 is only the section number used to facilitate locating methods. Permanent numbers indicate the year the method was approved (in this case 1999) followed by the order in which the method was approved that year (in this example, it is the 11th method approved in 1999).

When referencing AOAC^® Official Methods^SM, only the permanent number should be referenced as seen in this example:

(1) Official Methods of Analysis of AOAC INTERNATIONAL (2000) 17th Ed., AOAC INTERNATIONAL, Gaithersburg, MD, USA, Official Method 999.11.
