Every one of the Anker 's good ideas comes mired in caveats, and all the user tweaking in the world can't solve its fundamental design problems. The software deserves praise for making macros so easy to record and use, but otherwise, the feature set is pretty standard.

Method numbers indicate the year the method was adopted in this case followed by the order in which the method was approved that year in this example, it is the first method approved in The first set of numbers in the locator number indicates the chapter in this case, Chapter 5 , the second set indicates the subchapter in this case, subchapter 2 , and the last set indicates the order in which the method appears in the subchapter in this case, it is the seventh method.
The codification number is located at the top of the heading of the standard. In this example, represents the year in which stakeholders reached consensus on the standard. The second part of the codification number in this example, represents the order in which the standard was approved. These tools are needed by scientists who must meet the demands that modern society makes on the data produced. The 20th edition retains traditional methods and offers new ones utilizing stoichiometric and proximate measurements.
Beginning with the 19th edition, the Association included its voluntary consensus standards process as the primary step needed to support adoption of methods as Official Methods SM. This 20th edition, thus, includes methods approved using voluntary consensus standards. After 2 years, the ERP reexamines a method, and any new information, to ensure that, in practice, the method continues to meet the SMPR.
AOAC welcomes questions and believes that the questions and comments of users show that the methods are being used and continue to be relevant to the analytical communities. Agricultural Liming Materials 1. Fertilizers 2. Plants 3. Animal Feed 4. Drugs in Feeds 5.

Natural Toxins Dietary Supplements AOAC has evolved into an independent, third-party, nongovernment association of international industry organizations, government agencies, research institutions, and individual scientists, who network, engage, and deliberate on methods and quality measurements. AOAC provides opportunities for its members and scientists throughout the world to network, engage, and deliberate, thereby allowing AOAC to be in the forefront for developing international voluntary consensus standards for government and industry.
AOAC is a leader in delivering international voluntary consensus standards, Official Methods of Analysis OMA , Performance Tested Method SM PTM certification, laboratory proficiency testing programs, laboratory accreditation criteria, and scientific information and opportunities for global industry, government and regulatory agencies, and academic and research institutions.
Office of Management and Budget Circular A Standards activities are fully transparent and open. Consensus is documented and processes are in place to ensure due process and the opportunity to present appeals. AOAC has two programs by which methods are evaluated and approved. The OMA program is internationally known for its rigorous scientific and systematic scrutiny of methods and, because of the level of scrutiny, a high level of confidence, credibility, and defensibility is ascribed to resulting Official Methods of Analysis.
The PTM program has evolved into a premier method certification program for commercial and proprietary alternative methods. The PTM program offers certification as an endpoint for method evaluation or as an entry to method validation for programs requiring increased confidence and method reproducibility information. Other complementary products and services include validation protocol development and RI Contributing Membership.
The AOAC Laboratory Proficiency Testing Program has served as a tool for monitoring the competency of an accredited laboratory to perform specific tests. In addition to establishing technical competence for a laboratory, results from the proficiency testing program offer a new possible alternative approach for collecting reproducibility data to support an expert review panel ERP recommendation to advance a method from First Action to Final Action status.
The Technical Division for Laboratory Management TDLM helps laboratory managers improve the operations of their laboratories through the exchange of ideas and through professional development activities.
The Pharmaceutical Subcommittee was added in In , the Association entered into an agreement with ISO for the joint development and approval of common standards.
The Association also participates in the meetings of many other international groups, both private and government sponsored. Additionally, AOAC hosts specific standards development activities internationally.
Through the scientific symposia, poster sessions, workshops, forums, and short courses, meeting attendees enhance their analytical expertise, share their research, and strengthen contacts with their colleagues from around the world.
The Exposition held at the Annual Meeting features displays of the state of the art in laboratory products and services. AOAC stakeholder panels and working groups meet to deliberate on voluntary consensus standards. The details are dependent upon the scope of work to be accomplished. Sections provide opportunities for participants to share information, establish networks, expand leadership skills, and gain practical management experience.
Each AOAC Section is managed by a group of volunteer members, who facilitate a variety of Section events throughout the year, featuring technical presentations and discussions by leading local and national experts. The scope of the Journal describes original, basic, and applied research and recent advancements in the analytical sciences related to foods contaminants in foods, natural and industrial , fertilizers, drugs, agriculture, the environment, veterinary drug residues, microbiological methods foods, environmental samples , terrorist agents, botanical identification, and dietary supplements.
The Journal is a well-balanced publication, offering a wealth of titles relevant to the analytical community. Adding even more value to the Journal is the online product. ILM features news content specific to the work of AOAC and its analytical communities and contract-related efforts, such as agricultural materials, chemical contaminants and residues in foods, marine and freshwater foods, marine and freshwater toxins, dietary supplements, nutrients in infant formula and adult nutritional products, pesticide residues, disinfectants, food safety and security, biothreat detection, and veterinary drug residues.
ILM also features articles on the approval of analytical methods and test kits. The Board also appoints the Executive Director who directs and manages all operations, programs, activities, and affairs of the Association.
