1. General information

This document is designed and the certified value(s) and uncertainty(ies) are determined in accordance with ISO Guide 31^[1].

2.1 Intended use of the RM

- for laboratory use only

- calibration of analytical instruments。

2.2 Instruction for the correct use of the RM  

The compound should be stored at 2-8℃ in a dark place. Before usage of the RM , the compound should be allowed to warm to temperature(20±3℃). The recommended minimum sub - sample amount for all kinds of application is 100 μL. The expiry date of this RM is based on the current knowledge and holds only for proper storage conditions in the originally closed flasks/ packages.

2.3 Hazardous situation

The normal laboratory safety precautions should be observed when working with this RM.Further details for the handing of this RM are available as safety data sheet.

3. Certified values and their uncertainties

4.Discussion of traceability

This calibrant is certified on the basis of gravimetric preparation^[3]. Thus the certified value(mass concentration of U-[¹³C₁₄]-Alternariol,U-[¹³C₁₅]-Alternariol monomethyl ether,U-[¹³C₂₂]-Tentoxin,U-[¹³C₁₀]-Tenuazonic acid is based on the weighed amount of the starting material and is therefore traceable to the stated purity of the solid raw material. High purity material represents a practical realization of concentration units, through conversion of mass to molar quantity.

5. Confirmation of certified value by HPLC-DAD

The certified concentration of the gravimetric prepared solution was confirmed by HPLC-DAD against an independently prepared reference batch of unlabeled Alternariol,Alternariol monomethyl ether,Tentoxin,Tenuazonic acid.
