Based on the results from the statistical analysis of AOAC method efficiency software, all the parameters derived from the experiment have fulfilled the technical requirements of AOAC standards.
An overview on how your organization can obtain feedback for your method performance? Date: July 14-Aug 20, 2016. Feedback requested from: 30 collaborative laboratories and 45 laboratories using Cleanert TPT. The feedback information has been received from a total of 15 laboratories (excluding the information submitted online), including three overseas laboratories: Japan, Spain and Taiwan of China, and see the table below.
