1. Are the definitions specified in the SMPR used and applied appropriately in the supporting documentation (manuscripts, method studies, etc...)? If not, please explain the differences and if the method is impacted by the difference. 2. Is there information demonstrating that the method meets the SMPR Method Performance Requirements using the Reference Materials stated in the SMPR? If not, then specify what is missing and how this impacts demonstration of performance of the method. method performs within the SMPR Method Performance Requirements using the Reference Materials stated in the SMPR? If not, then specify what is missing and how this impacts demonstration of method performance. 3. Is there information demonstrating that the method performs within the SMPR Method Performance REquirements table specifications for all analytes in the SMPR applicability statement? If not, please specify what is missing and whether or not the method's applicability should be modified. 1. Based on the supporting information, were there any additional steps in the evaluation of the method that indicated the need for any additional precautionary statements in the method? 4.

Yes.

Yes. 3 NIST SRMs were used for demonstration of accuracy. Determination of theanine in all 3 materials was within uncertainty of the assigned values.

Yes. 3 NIST SRMs were used for demonstration of accuracy. Determination of theanine in all 3 materials was within uncertainty of the assigned values.

The method only addresses the determination of theanine. Method does not address determination of catechins, methyl xanthines, or theaflavins.

The method is very specific for theanine and it does not make sense to extend the applicability to the other analyte groups.

No.
