AOAC RESEARCH INSTITUTE AOAC OFFICIAL METHODS OF ANALYSIS (OMA) OMAMAN-24: DETERMINATION OF TOTAL SULFUR IN FERTILIZERS BY HIGH TEMPERATURE COMBUSTION

regarding the manuscript comments and coordinated distribution of samples to the instrument manufacturers so as to collect data based on the above comments. In September 2016: The method authors along with instrument manufacturers attended the ERP session and presented on how the method works with the new instruments and some initial data collection. The manuscript and method revisions were not submitted at that time. In January 2017: Revised method submitted by Elementar Americas. It includes references to interlaboratory studies; however, this work is not yet complete. RECOMMENDATION: Reflective of the unanimously passed motion moved by the ERP in September, 2015 to edit the method prior to First Action publication to accommodate sample preparation, instrument conditions, safety, and to allow for other instrument manufacturers : ERP members will need to confirm whether OMAMAN-24, which was moved to First Action Official Methods status in 2015, is now ready for publication in the Official Methods of Analysis of AOAC INTERNATIONAL. Please review the attached document and make your recommendation. If this method has satisfied the requirements of the Expert Review Panel as noted above, please indicate by selecting one of the following options below by copying and pasting in your reply email: • I AGREE that the method as revised, Total Sulfur in Fertilizers by High Temperature Combustion , is now ready for publication in the Official Methods of Analysis of AOAC INTERNATIONAL. • I DISAGREE that the method as revised, Total Sulfur in Fertilizers by High Temperature Combustion , is now ready for publication in the Official Methods of Analysis of AOAC INTERNATIONAL. If you select, “I Disagree”, please indicate what part of the motion has not been fulfilled based on your review of the revised method.
