Sampling

In case the samples to be tested are goods in containers (e.g. beverages in bottles, rice in bags) ideally an unopened original container should be sent in.

In case the samples are taken from loose goods (e.g. grain from a particular batch), it is recommended to collect small quantities at different locations and blend them into a single sample.

In case of countable goods (e.g. eggs, apples) it is normally required to provide several pieces.
After our scientific experiences, the following recommendation can be given for a representative sampling session on a field:

• 7 samples should be drawn along the field's diagonal line or
• 12 samples should be drawn at a distance of at minimum 5 m away from the field boundary distributed around the entire field.

For the reference sample acquisition it is absolutely mandatory to obtain authentic samples of a location. There is a risk not to be able to obtain authentic samples if they cannot be collected at their location of origin. However, the risk can be minimized by a careful selection of the sample source or by collecting a greater number of reference samples coming from different sources, respectively.

If the analysis is to be conducted because of a suspected wrongful declaration and filing a law suit is considered, it can be advisable to plan already the sampling step according to officially accepted guidelines.
